Anyone ever buy that RP test brass in 9mm DK sells? I got some, and it's nice, but about 30% of the cases wouldn't go into the shell holder. The primers were bulged. I let them know, and got a reply, but they don't seem very interested in the problem. Ultimately, I ended up getting the primers out by putting the cases on top of the shell holder, which was somewhat sketchy, but worked.
FWIW, I also bought some of the same brass, but in 40 S&W. That batch had a 9mm, a 10 mm, several 357 SIG, and most concerning, several 357 SIG cases on which the bottleneck somehow got removed, making it very hard to tell from a 40 case.
