Springtime in the Spring

First, it has been a very busy month!

I mentioned last time that the trigger safety on my primary IDPA pistol had gone on walkabout. This was discovered before a regular Wednesday night match and later research reveals that I had not noticed it was missing for at least a week and probably two. Well, I made little of the missing part, completed the match, split the collected brass with another loader and went on with life, including ordering a replacement trigger, which Zev thankfully covered under warranty exchange.

A couple of days later, I was cleaning that brass and I was kinda vaguely on the lookout for the safety and extremely to my surprise, it was in that brass! That means it was lost there at or before the lunchtime range trip in which I snapped a pic of the pistol, survived who know how many times sweeping the floor, including a couple of IDPA matches, only to end up the the *half* of the brass swept up on *the night* I discovered it was missing. Sadly, the lottery tickets I bought when I realized the pretty low probabilities of all that happening did not pan out as well.

Even before the trigger fiasco, I had decided that I would attempt to shoot CDP division for while, which basically means either 1911 and barney mag or the Glock 21. I went for the Glock angle.

My Glock 21 had Warren Tactical Sevigny sights on it, which are very nice but that I personally don’t care for. I am kinda spoiled to dots on the rear sight and I had some delay in finding a sight picture quickly. I picked up a set of TruGlo TFX Pro sights and swapped them out. Now that they are in place, I kind of wish I’d put the TFX Pro sights on the G20 and put the older TFO sights on the G21. I may still.

In any case, it turns out that between the “wrong” trigger and the increase in power factor for CDP, I was kinda crappy at CDP. After giving it a try for several matches and growing to hate it, I decided the retraining curve was sharper than I wanted to tolerate for the leadup to three major matches in 3 months, so I switched back to the G20 shooting soft 40S&W and started having scores that didn’t piss me off. šŸ™‚

I went to what is officially the most distant IDPA match that I have gone to *for the match*. I did manage to take in a local match in Phoenix last summer while I was there for work and that was farther away, but this was a level 3 IDPA Regional Match to benefit the American Foundation for Suicide Prevention. The event raised $7000 for the AFSP. When the dust first settled, I was 7th in my class and division. While we waited for the scores to be finalized, it turned out that one squad’s scores for Stage 8 had dissolved into digital dust somewhere. At first, they had requested that squad return to that stage for a reshoot, but it turned out that some of those guys had left for the day. They decided to throw that stage out, which did result in a little bit of cheering. Apparently it was not a great stage for many shooters. My own time jumped up quite a bit. It was my worst stage as well, though other people must had done especially poorly on it. When the dust settled for real this time, I had a better score but had gone down to 9th. Obviously, at least a couple of ESP Sharpshooters had shot generally better than I did, but must have really stunk up Stage 8.

For the matches leading up to the Arkansas trip and for that match, I had worked up a nice load running 130PF at home, just to be sure I had a little margin for the chrono in Arkasas. I loaded 300 rounds into boxes that were marked specifically for that match and eight more for the several matches before going to Arkansas. All of this ammo is ideally the same.

For the first match after I got back from Arkansas, I had some intermittent failures to feed. In a couple of those stages, it was just about like I had a bolt action Glock, having to bump the slide or rack out what felt like after every round fired. It was painful!

Between stages, I cleaned the barrel. The pistol had not been cleaned since the MVSA match and while I had never had that much trouble with it being just a little dirty, it seemed to help some. Then I noticed that it might be one particular magazine. It’s just hard to troubleshoot during a match.

It occurs to me that some of these magazines are approaching more than 10 years old and still others came to me from elsewhere, so no telling how old they are. I decided to do a full clean and recondition of all of them, complete with replacement springs. A 10 pack of Wolff +10% magazine springs is less than $50 and less than the individual cost of ordering 7 springs. They should be in soon.

 

May The Force (Gauge) Be With You

I mentioned in a previous post a while back that I acquired aĀ Reed SD-6020 force gauge. It is a fun and interesting tool. I have used it mostly for measuring springs thus far.

I have a workable technique for measuring captive recoil springs a la Glock. I clamp a Glock slide my workbench then put a spacer under the force gauge such that the sensor is reasonably level with the hole in the slide. In this case, a tablet of graph paper I have is the right size. Then I can slide the gauge back and forth compressing the spring and read the weight.

Here a stock Glock spring, with its plastic guide rod, rings out at 15.32 pounds. To take this measurement, I compress the spring until it locks solid, then back off a hair. Yes, a hair, enough to tell that the spring is no longer compressed completely, a small fraction of a millimeter. This seems to be the valid place to measure because it corresponds with theĀ  maximum 2 inches of travel that the slide does when installed on the pistol.

I have several aftermarket springs with stainless steel guide rods. At first, I bought stock weight springs. Then I started handloading specifically to soft recoil and found I needed lighter springs to tune the pistol to run the lighter loads. I remember ordering a 13 pound spring and I thought I had ordered an 11 pound spring. They are marked in paint colors out of the package, but the paint is long gone after using and cleaning the pistol many times. However, I could not find any springs that went below about 13.5 pounds or so.

Soooo… I ordered a new 11 pound spring. Guess what? It measures at over 13 pounds.

The other measurement the force gauge has been nice for is striker spring weight. I clamp the slide down and use a hook adapter to pull back the striker. My Glock 21 striker comes in at 5 pounds

The Glock 20 slide with the nicest trigger pull is only 3.6 pounds.

After I installed a Zev Fulcrum Ultimate trigger kit (trigger, springs, striker, etc) I knew that I started getting light primer strikes, especially with ammo I had loaded with S&B primers, so not at all surprised to find this. I had a few striker springs, presumed to be stock weight from previous upgrades, and Glockstore competition spring kit, so I swapped some springs around to get a 5 pound striker spring in the Carry Optic slide and 4 pounds in the regular slide, though I should probably swap those. The trigger pull predictably went up. Shrug. It remains to be seen if that solves the light strike issue on my S&B primers. They are sitting in storage at the moment because I never want to knowingly introduce an ammo problem if I can avoid it.

Speaking of the Zev trigger, at a match last night I struck up a conversationĀ  about trigger work with a buddy at the safe table. In exchanging pistols in the discussion, I noticed that the trigger safety was missing from the pistol. We decided that it would be fine for the local match, but that it will definitely need to be fixed before any major match and really needs to be fixed regardless.

It is a mystery exactly when and where it was lost. I have a picture of the pistol from a range trip a couple weeks ago and it appears to be missing even then.

The only previous picture I have that shows the trigger was from last August and the safety was present then.

Upon close examination, you can see that it appears to be held in by a set screw, which is missing. I have not adjusted any of the adjustments on the trigger, but I have used the ultrasonic cleaner on it. I wonder if that eroded enough red Locktite away to let the screw come loose? I will check in the cleaner tonight on the off chance that it came loose *in* the cleaner.

I contacted Zev about getting the parts sent to me. For liability reasons, what with it being a safety part, they are unwilling to send me the parts. On the other hand, they will exchange the whole trigger and bar for a new one. They sent me an RMA and mine will be on it’s way to them tomorrow. They promise I’ll have the new one back 1-3 days after they receive mine.

Luckily, I do have two interchangeable frames. Even though the Glock 21Ā  frame has a stock trigger, it is as smoothly polished and lightly sprung as a stock trigger can be, so I will still be able to shoot.

The Slides of March

One of the things that happened in January is that I got shot.

Well, kinda.

A bit of a bullet bounced back and dinged me pretty good.

I lived, though it did sting a bit.

I let myself run out of 180g 40/10 Cimarron bullets. I like them overall and they shoot really well, but they are a little fussier to load. While waiting for a big order of Xtreme 180g bullets to arrive, I switched the press over to 9mm and loaded a bunch of 135g 9mm Cimarron bullets. I loaded 600 pretty much in one sitting.

Right about this time, there was an interesting discussion on the Cross Timbers forum about sorting brass before loading and the reasons some people would do such a thing. There are basically two schools, those who want to make the most consistent ammo possible and those for whom the benefits are not commensurate to the required effort. I am in the middle somewhere, though closer to the latter.

The discussion had a significant bent towards weeding out known troublesome brass, such as certain brands that have a stepped interior or crimped primers, before loading them. Since I had 600 rounds of ammo that had been loaded and passed all my QA processes, I counted and sorted them. Of course, it is a slightly skewed statistic for the purposes of the forum discussion because these 600 rounds were all *good*, with no failures. On the other hand, in 600 rounds of loading, I probably didn’t have more than a dozen or so that were culled during loading (mostly crimped primers or obviously damaged cases) and fewer than that made it through the press to fail QA.

About 52% of the ammo was one of 4 headstamps and more than half of that was one or another form of Winchester.

One of the most interesting statistics to me was that there were 26 of a specific WCC headstamp that were all originally crimped primers, but obviously all of them loaded without issue. I’m presuming that some of them may have been previously loaded on a press that swages primer pockets or maybe the crimp happened to be of a suitable symmetry to reload without issue.

Until recently, I have ordered bullets in 500 and 1000 quantities only, mostly just to keep from spending a lot at once. The long term economics are a little better for the larger orders, at least in terms of shipping costs, especially when the seller runs a shipping special.

I noticed that, for X-Treme Bullets at least, the bulk quantities of each bullet weight seems to be driven to keep the package weight right about 65 pounds.

115g  9mm x 4000 = 65.7 pounds
124g  9mm x 3750 = 66.4 pounds
147g  9mm x 3000 = 63.0 pounds
165g 10mm x 2750 = 64.8 pounds
180g 10mm x 2500 = 64.3 pounds
230g  .45 x 2000 = 65.7 pounds

I did some digging on UPS and FedEx websites and I could not find any magic price increase at or around 65 pounds. On the other hand, the price the website quoted for me to ship my 65 pound package was 7 times the flat rate $5 shipping for that order, so it may be part of a contract between X-Treme and UPS. In any case, a 65 pound bucket o’ bullets is pretty heavy.

As is my preference, I spent a little time splitting them into 100 round packages for my personal convenience. There were 2509 in the bucket. šŸ™‚

 

Happy New Year!

It was a busy holiday season, no doubt! I don’t know if I will cover everything or not…

Ocotober was crazy, though.

Way back in October, before my last update even, I picked up a VibraPrime, an interesting device intended to help one spend less time filling primer tubes. As described, “The Vibra-Prime can load 100 primers into a primer tube in a matter of seconds with its unique motorized agitation mechanism.” For *that step* of the process, actually stacking primers in a tube, it works as advertised. However, in my experience with it, the entire process from a box of primers to a tube ready to load into the press, the VibraPrime is a fussy process with too many steps.

The VibraPrime tray is much like a standard flip tray. It is sized so that most primer packages will fit over it so that when you load it, you can shake it to flip any errant primers to the proper orientation, anvil side up. You then put slide the tray into the pistol gripped motorized vibrating thingy and attach what I am calling the intermediate tube to the bottom of the vibration unit. Now you activate the vibration unit by holding the trigger and tilt the unit to guide the bouncing primers to the mouth of the tube. You can optimize the angle and technique with just a little practice. This part of the process is indeed quick, 10 to 20 seconds at most. Then you remove the cap of usual primer pickup tube, mate it with the adapting sleeve on the intermediate tube, pull the wire pin and drop all 100 primers into the pickup tube. Replace the cap and you have a filled tube. With practice, you get the the whole process down to about 90 seconds

Orrrrr….

Use a standard primer flip tray to right the primers, place the cover over them, invert, remove the tray and pick up 100 individual primers directly into the pickup tube in about the same amount of time, maybe less. No batteries, no intermediary tools, more free brain cycles to use to think about the analytical algebraic topology of locally Euclidean metrization of an infinitely differentiable Riemannian manifold.

Where I think it could help is scaling. If you have a dozen tubes to fill, you could probably do them faster than by manual means. For me, however, I don’t think I gain much from the machine.

I already had some nice bright LED lighting on my press. The Inline Fabriction light mounts in the center hole of the tool head, shining directly down on the shell plate. This was a tremendous improvement over my clamp light, which provides a lot of light itself.

Now I have added the UFO 550 from KMS.

From this angle, it looks like I’m about to be vaporized in the evil scientist’s invention.

Note that the Inline Fabrication light is still there. More light is always better.

The UFO light, besides just throwing more lumens, also has a bit that goes down the front of the frame, on the right side in the pic above. This lights up the primer slide, which is normally in the shadow of the shell plate.

In mid-October came theĀ Lone Star IDPA Championship, which was my first staff experience in a major match. In spite of being pretty much fully into the throws of seasonal allergy trigger asthma, I had a lot of fun and learned a lot about what it takes to put on a big match. I knew there was a lot to it, but some of the specific details were enlightening. I really enjoyed getting to see almost every single competitor shoot, other than the staff members that were on other squads on staff day.

As for my match performance, I have definitely done worse, 95th overall (which doesn’t really mean anything), 14th in my class and division and somewhere in the mid-20’s & 30’s for any given stage. I had 11 down on one stage, single digits on all others and no procedural errors at all.

Nothing much for me on the prize table, just some hot pink magazine basepad markers that I put on the the G19 mags.

October also marked the last match held at the financially troubled Total Shooting Sports. It was a nice venue and the Monday night matches we had there are missed and have not yet been replaced.

When I got my FX9, did a quick and dirty sight-in and actually shot a couple of indoor carbine matches with it, but it was not really on at all. Miss enough heads or hit a few non-threats and you’ll want to spend the little while it takes to sight it in. I eventually got a handle on it.

One of my coworkers lost his Dad. As part of the resolution of the estate, the family sold all the belongings in his house and the house itself. He had been an avid sportsman and woodworker, so there was deep sea fishing gear, firearms and a shop full of tools and supplies. The guns went pretty quick, but I did get a very nice Remington 700 BDL in 6mm Remington, my first bolt action rifle ever. At this writing, I have yet to fire it…

You may recall that I shot my chronograph some time back. It was really only cosmetic damage, but I secured a replacement case for it. There is not much to the inside of one of those…

 

Minor FX9 Issue

It took me a while to notice it, but the magazine release on the FX9 was a little sticky. The lever pivots on a pin that I was unable grab and pull. Eventually, however, repeated operation of the lever worked them pin out enough to pull.

The red area is Sharpy stand-in for Dye-Chem I applied while the lever was still installed. The sticky bit was still unreachable inside the lower before the pin was removed.

Once it was out, it was a simple matter to remove enough material to stop the scrape.

All reassembled and reliable, with any of the magazines I have, regardless of brand. Woohoo!

 

Far Too Long!

A lot has happened in the nearly 4 months since my last post.

Polycase is now selling their lead free projectiles for handloading. Sadly, they are not particularly cheap, 18 to 22 cents apiece for 97 grain 40/10. The minute (literally) that I read the notice from MidwayUSA that they were selling them, I ordered 1000 for $188. That was with an introductory discount. They are $207/1000 as I write this.

To get them running at least 125 PF, I had to crank up the Winchester 231 powder to 6.1g. Depending on the cost of brass, they ran from 25 to 32 cents per round. Performance is good. That big ol’ charge of powder makes a pretty good boom and flash, but recoil is essentially the same as my other competition loads. The peanut gallery complains about their ears, though. šŸ™‚

Interestingly, the bullet weight had less influence than expected on velocity. I started with the default 4.25g to 4.35g charge that I use for 180g bullets. The 180s run about 790fps for 144PF. However, that same charge under the 97 grain lead free was not very much faster, just over 800fps. To make 128PF, they need to be pushed to about 1300fps, thus the increase to 6.1g.

They have served me well. They make clean holes in paper, knock down steel reliably and generate conversation occasionally. I don’t have many of that first order left and while I probably wont shoot it all the time due to cost, I also understand that the price will never come down if nobody buys them.

I picked up a Ā Freedom Ordnance FX-9 9mm carbine in a group purchase. The quantity discount was such that rifle, shipping and FFL fees were still less than the listed price for just one. It appears to be generally well made. Some of the other people in the club have upgraded and accessorized way more than I have. I added a Vortex StrikeFire 2 and MagPul MBUS and later an M-Lok rail and a flashlight for the first ever CTASA low light carbine match.

The only trouble I have had with it was that it doesn’t seem to like fully loaded 30 round magazines. My first trip to the range with it, I had two issues with the supplied SGM magazine. The first issue was that after a couple of rounds were fired, the floor plate came loose, dropping 20-something rounds and magazine parts all of the floor, resulting in an RO stop of the range to retrieve the parts. The tube remained in the gun, but all the internals fell. Later in the same range trip, the magazine fell out two or three rounds into a full one. I declared the magazine to be junk and just used the collection of magazines for my Glock 19. They seem to have worked fine. In one match, I loaned it to someone and it dropped a mag on them, but we blamed it on a lack of familiarity with the platform.

Recently, however, I have discovered that the magazine release button/lever is a little bit sticky. The self-disassembling first time use of the SGM magazine would not have been caused by that, but other times when the magazine has fallen out could be that release button. I will address that for sure.

Ammo-wise, it runs on almost everything I’ve put in it. All the factory ammo I have used, all 115g, and my 147g handloads for the G19 run perfectly. Some really soft 147g had a couple of FTEs per magazine, so that’s definitely too light. Some really soft 135g handloads ran reliably and recoil is similar to or maybe less than the 10/22. I have not chronographed those as yet, but since IDPA PCC requires a minimum of 135PF, I suspect they will come in too light.

Speaking of chronograph, my poor chrono was shot twice within three weeks. First time, a buddy came out to work up and load a bunch of 45 Auto. One time, the pistol was pulled a bit to one side and the bullet caught one of the screen supports.

It only bent the wire; about one minute on the anvil and it’s good as new.

Only last weekend, I had my turn. I tried out my usual competition load in the little Kahr CW40. The Kahr has a reeeeally long trigger pull and having immediately before shot the Zev in the G20, I pulled it down a bit, enough to hit the body of the appliance.

Happily, it is only cosmetic damage and it works just fine.

I found a heck of a deal on bullets. Xtreme Bullets has a discount house called Reloading Valley that sells, among other things, pulled bullets. I ordered 10 bags of 250 mixed 165/180 and mixxed RNFP/HP. They work out to about 6 cents apiece.

Since they were mixed in both weight and type, I commenced to sorting them manually.

The distribution was essentially 99.9% 180g, maybe 20-30 165g bullets in 2500. Of those, about 1/3 were HP and 2/3 were RNFP. The pulling hardware damaged a few, mostly the HPs. Most of the RNFP have only a faint mark from the case crimp.

I have loaded about 500 thus far. There have been a couple that didn’t pass QA and at least a one that didn’t feed right. All in all, I’m pretty pleased with them.

Along with PCC, IDPA now has a provisional Carry Optic division. As luck would have it, I already had a suitable optic and just had to reinstall it on the slide it was on when I got it.

 

First and… FIRST!

The Sunday of Memorial Day weekend brought theĀ 2017 Republic of Texas IDPA Championship Match. We had a great squad and there was much enjoyment.

The day started pretty well. I got there early enough to be 4th in line at the check-in. That is not my usual experience. We got started about on time.

We started on Stage 9 and I started with 28:49 and 1 point down. The rest were 4 or 5 down, with one 10 down, but there were no misses. There was one hit on a non-threat. There were two stages with a steel activator in front of a paper non-threat. If you don’t hit the steel on the first shot, it’s pretty much guaranteed to have a HNT. All in all, about 30 down for the whole match at that point.

By now, we have rocked around to Stage 3.

Pretty straight forward 5 threat targets, including the disappearing popup and all paper targets require 3 rounds each. However, there is one tricky caveat. Since you are addressing the targets from SP in barricade order, you must engage the activator steel, then the popper, THEN you can move to the other position to get the popup target. Ironically, I did ok on this gamey bit. On the other hand, three headshots on the first target all hit just in the hard cover, so 15 down there.Ā I hit the activator, but missed the popper, so I would have to go back for it later, but it was engaged so no PE. I made it to the pop-up in time to get it with a 0 and two 1s, but for some reason I only sent two at that other other paper target on that side before running back to make up the steel. So I scored 4 on it, plus 5 for the “miss” plus 3 for the PE. Add in the 1s on the other targets and suddenly this stage that I shot in 17:65 is 34 down.

I figured at that point it was probably not recoverable and I was out of any running for 1st or 2nd (needed for a bump) and was now just there to shoot. We broke for lunch, and when we came back, I was back to normal, mostly getting 5 down in reasonably short time on the remaining stages.

We finished and packed up and enjoyed some tailgate fellowship while we waited for the scores to be compiled.

That gave us plenty of time to beat ourselves up for our various performances. Finally they announced that they were posting the scores. A couple of us decided we would wander on down there and check it out anyway. By the time we walked down to the leaderboard, a polite mob had formed. It look a few minutes to drift through the throngs, only to discover that I needed to be about 5 feet to the left to see the right sheet.

When I got close enough, I had trouble finding myself on the list. Turns out I started too low.

It took quite a while to convince myself that it was correct. It was.

First Place, ESP Marksman. With a bump to SharpShooter.

Firsts and Fifths

There has been a lot going on, enough so that I haven’t had time to catch up with the updates…

I placed in a major match for the first time ever. Fifth place, but placed!

In following tradition, here’s a semi-artsy photo of my award and still-dirty gun. šŸ™‚

Regardless of the semi-miserable cold and muddy conditions, the pistol has a tiny bit of mud on the grip and the Polycase Inceptor ammo burns pretty cleanly.

The ammo ran absolutely trouble free, too. As expected, there was a bit of conversation at the chrono table and mock resistance as they had a nice chart of common bullet weights and the minimum velocities required to meet power factor. There was not a chart entry for 97 grains, so a bit of math ensued. 1288 fps required; 1388 and 1401 achieved for 135 PF.

It never really *rained*, but we had mostly constant drizzle from about 9AM until about 1PM. For me, the peak of misery was around Stage 12. By then, no targets were dry, no tape would stick and every step added a pound of sticky mud to the bottoms of my shoes.

The start position for stages is often marked with foot-shaped cutouts for the shooter to stand on. Believe it or not, there is a set of them in this picture.

Match results were not too shabby, especially considering my recollection of my previous run at Silver Dollar in 2014. However, upon closer analysis, the 2014 scores were maybe not as bad as I remember. Raw and final times were actually similar, though the rules in effect in 2014 meant that it took 137 points down to be similar to only 80 points down in 2017.

In any case, first wood is still first wood and I am very happy about it and the weather only made it more valuable.

The rain was gone, but it was pretty windy on Sunday, too.

In preparation for Silver Dollar (and just because), I ordered a Zev trigger for my Glock 20. I ordered the Fulcum Professional Ultimate package, which is the non-adjustable version with all the related parts. It was hoped that it would arrive in time for me to install it and shoot in a local match or two before Silver Dollar. When it still had not shipped by the Thursday before the match, I contacted Zev about it. Turns out that they were backordered from their supplier on parts for the non-adjustable trigger. They upgraded my order to the adjustable version and credited the shipping charges. While it was the Monday after the match before I received the trigger, I ended up with the arguably better version for less money.

It took longer to clean the gun before installing the trigger than it did to install the trigger. Well, unless you count the time spent looking for the tiny striker spring cup half that I dropped. It seems like it might be a good idea to have spares of those.

The stock trigger on that particular pistol is/was well polished and broken in and had already been tweaked as much as possible, so the Zev trigger did not make much difference in the pull weight, 3 to 3.5 pounds. The new trigger does have a crisper release, a shorter reset and the trigger shoe itself is nice and wide and flat, so that 3 pounds feels like less. A lunchtime trip to the range on Tuesday revealed that it works very well.

I have a new toy, er, tool. I have wanted a force gauge for a while. I have a couple of practical uses for one, but mostly I am just curious about everything and want to know.

This one is a Reed SD-6020, a 20 Kg capacity force gauge. Anyone of a less scientific bent would probably call it an overpriced digital scales. šŸ™‚ Due to what I can only call a fluke in the pricing structure at Amazon, this unit was listed at about $144 instead of the usual $535. The listing did not indicate that it was used, though admittedly, there was none of the usual new device additional packaging, like poly bagging around the device, and it had a battery installed. Doesn’t matter to me!

The first practical use I have for it is to verify the weight of the recoil springs in my various pistols. For proof of concept, I took a quick measurement of the stock spring in my Glock 19. I used the hole in the front of the slide as a guide and pressed the gauge against the other end of the captive spring assembly. I found that just short of full compression, it read just underĀ 16 pounds, which is about what was expected. I have not found a lot of really authoritative info about the stock spring specifications other than in the description of aftermarket parts. There does seem to be a consensus that 16 pounds is likely.

I could not remember whether the reduced spring I have been using in my G20C for low recoil 40S&W was the 11 pound or the 13 pound. Holding the slide in a rubber jaw vice freed up both hands to compress the spring, and after several attempts, I was able to compress the spring then carefully use my left hand to snap a pic without moving the gauge two millimeters and having the spring launch across the room.

I took several measurements that ranged from 13.49 to 14.1 pounds. I presume those could be within expected tolerances of 13 pounds or maybe it’s really a 14 pound spring that was in the 13 pound package. It is definitely not 11 pounds. With the 11 pound spring, I may be able to experiment with ammo running less than 125PF, particularly if I want to tweak ammo for use in a BUG gun, assuming I can adjust my Kahr CW40 to comply with the new rules. In any case, I will locate and measure all the recoil springs I have. Expect a future post on the subject.

Last Wednesday was the first Low Light match at Defender Outdoors and so far as I can tell, the first one at all since August 2016. Except for one stage which allowed a rail mounted light on a gun, I held my light in my left hand and shot strong hand only. There were a couple of misses, but generally, it was not a bad plan.

 

 

 

Fine Tuning

I am pretty comfortable with my current 40S&W load 180 grain bullets on 4.35 grains Winchester 231. It’s a pretty solid 800 fps for 144 power factor and 256 ft/lbs muzzle energy. It runs the pistol well, too.

I set up the chronograph and got ready to play with the powder measure. I threw 10 loads of powder, weighed it and divided by 10. When I set the measure up, this method showed the charge to be 4.35 grains. It came out this time as 4.25 grains, so I ran it again and got 4.25 grains again. Now, the whole assembly had been moved to the loaner press and back, so a small change might not be surprising. Then again, I should have spot checked it at least after each move. Next time.

So, I reduced the charge, weighed it and failed do document the weight for it and the next three charges. At least I did document the average velocities for 5 shots.

773 fps = 139PF = 239 ft/lbs

762 fps = 137PF = 232 ft/lbs

750 fps = 135PF = 225 ft/lbs

735 fps = 132PF = 216 ft/lbs

I landed on 3.85 grains for 724 fps, 130PF & 209 ft/lbs. I ran about 20 rounds through the chrono to verify that it was stable at this velocity.

I like to experiment with loads and bullet weights, so I left the charge at 3.85 grains, but loaded ten 155 grain plated bullets. The average came out to 643 fps, 99PF & 142 ft/lbs. As it turns out, 142 ft/lbs is not enough to run the pistol. In fact, it exactly zero rounds ejected, though a couple did open the slide a bit. The brass showed soot smudging on the outside. I think the surprisingly large drop in velocity and the sooty cases indicates that the pressure dropped significantly, maybe because the 155 grain bullet is quite a bit shorter than the 180, but I have them seated to the same OAL, leaving a larger space in the cartridge.

The 165 grain poly-coated bullets did a little better, 748 fps, 123 PF & 205 ft/lbs. The pistol ran just fine, but that power factor is a little too low. I should be able to tweak the charge for all those 155 and 165 grain bullets I have left from when I started loading 180’s. šŸ™‚

 

Dillon Delivers

Man, you can’t believe anything those guys say. First, they say it will be 2-3 weeks turnaround. They received my press on April 4 and I got FedEx notification that it was shipped back on April 7.Ā THEN, FedEx says it will arrive on the 12th, but I had it on the 11th. How am I supposed to complain now?!?

If you look really close, you can see the color difference on the replacement crank and links. The frame has some slight yellowing on it, making it ever so slightly greenish.

There was a list of the parts replaced, including the clearly labeled primer shield and many small bits.

Before I reinstalled my press, I cleaned up the borrowed press within an inch of it’s life.

Before:

After:

Swapping the presses out was largely trivial; afterall, I’ve done it a few times now.

I added one accessory that I had ordered before the old press broke, a JW Systems Primer Track. This is basically just a replacement primer track bearing (which is a steel plate that sits under the primer slide) but it has a ball bearing roller added to help stabilize the primer slide.

As expected, I did not have to adjust anything on the top end to begin loading again. It just works, ya know.

I had the afternoon off last Friday and one of the things I tackled with that free time was to disassemble a pretty good sized bin of loading errors. They were mostly 40S&W and a lot of them predate the Dillon press, and thus most of them were primer issues from the Lee Press. I used a Hornady collett puller for most of them. That is by far the quickest way to pull a lot of bullets. Once adjusted for what you are pulling and getting into the groove, it’s about 5 seconds per cartridge.

Some of the primers were crushed into the pockets crossways and thus would not slideĀ into the shell holder for the collett puller, so I had to use the intertia puller. Happily only a dozen or so needed this special care.

I pulled a few 155’s, a few 165’s and a bunch of 180’s.

The scrap brass bucket grew, too.

Here’s a couple hundred grains of TitePowerWinGroupPistol231.

Between the damaged brass and the damaged bullets, I had roughly what was needed for about 150 fresh cartridges. šŸ™‚

While I had the interia puller in hand, I tried once again to pull one of the polymer bullets from the Inceptor lead free ammo and much to my surprise, it worked this time! I didn’t count, but it was about 50 strikes of the puller against the end of a 2×4 in the framework of my workbench. The previous unsuccessful attempt was struck against the concrete floor. Maybe the deadblow effect worked better than the rigid bounceback.

As I plan to shoot this ammo in the upcoming Silver Dollar Championship, I think I will keep this bullet or see if I can pull a couple others to include with my chrono samples. I have already spoken with the Match Director about the possibleĀ difficulties in pulling a bullet for the test and he said to bring it on!
