Tea and Crimpets

… except no tea…

You may recall that I had a quality control issue with a couple of batches of 40 S&W. They were not crimped properly, so they appeared to be oversize and would not go battery. I purposefully did not purchase the single shot version of the Glock, but now I had one 🙂

I set up the press with the seating/crimping die only and backed the bullet seat ram way out so that it was crimping only.

I didn’t feel warm and fuzzy dropping loaded rounds, nose to primer, down the feed tubes, so I removed them and just set each in place as shown.

After tweaking the crimp over a few rounds, I tested each of the first 150 by fitting them in the chamber of my Lone Wolf barrel. If it dropped in and poured out, I called it good. With those working flawlessly, I started testing five random cartridges from each finished box.

When I got to the batch of nickel plated cases, I found that they were much better crimped. The press had been reset between those batches, so I just set it better on that batch.  Most were either fine or maybe had the slightest drag in the chamber. I ran them through anyway, again testing five from each box after recrimping

It took about 5 minutes per box, start of one to the start of the next. All tolled, about 1700 +/- recrimped in about 4 hours. Just to be thorough, I spot checked about 5 boxes of 10MM, but they have all been working anyway, so there was probably no need. Now to see how the shoot in a match tomorrow evening.
