Interesting thing happened today.

I made a bunch of .45 ACP ammo. I made lead rounds with Zero bullets, and I made defensive rounds with Hornady XTP's and new brass. When I made the ammunition, I kept a .45 barrel by the press, and from time to time, I checked to see if the rounds would drop into the chamber. They did.

Today I shot a gun with a different barrel, and the Zero ammo did not want to go into battery. The slide kept sticking about 1/8" back. I was able to push the slide forward when this happened, so the ammunition was usable, but it turned a semiauto pistol into something more like a bolt action.

When I made this stuff, I tried not to crimp any farther back than I had to, because over-crimping can make the case too wide. It looks like I went too far in the other direction.

So. Does this happen to other people? Should I have been using a caliper or micrometer instead of a barrel to check the mouth width?

The XTP ammo shot just fine.
