Took 50 new hornady .460 S&W cases and worked them into .45colt "magnum" shot shell cases. I wanted to fire form them a bit, so I pushed a 1/2" long wax wad cutter into the case mouths, primed them up, and went to fire them at a cardboard backstop.
Noticed after firing a couple of them, the wheel gun took a lot more force to cock. Stopped, and (tried to) drop the cylinder out, and man it was stuck. Finally got it out, and noticed that on the two fired cases, the primers had backed out, and were rubbing against the inside of the recoil shield.
Thought it was bad brass, as the OD of the primers was .210" on my calipers. So I tried a couple with regular .45 colt starline cases, and the same damn thing happened. Primers backed out again!
I have already run through the first 1000 of these primers in .45acp. About half of them I've shot and the other 500 or so are still waiting on me. I never noticed any issues with them in either the 1911 or the sig p220. Never bothered to look at the fired acp cases to see how far they backed out (if at all), as there was no perceived need to inspect prior to de-capping and cleaning. Now what?
So the questions are: Is it ok to continue using these in the semi-autos, or have I been really lucky with the first 500 I ran through them? With mid level loads, what is the potential catastrophic failure mode?
TIA
