Perplexed about de priming brass...
Got 1000 nickel plated +p 38 Special cases from a member on here a couple of weeks back. Mixed headstamped, RP or FC or WW. About 10-15% of the primers won’t come out, the tops are getting “popped” off.
I am using a Lee Universal Depriming Die. Switched to a RCBS carbide resizer/depriming die, same thing. Switched to a Lyman die, same thing. Even went to the Lee Whack A Mole setup and same thing. Four different dies and the same “popped” off primer tops. Speed was varied as well. Slow or fast, same results.
What’s deal? Ultra sealed primers due to being nickel and +p and hard to get out? Crappy primer material? WTH?
