I find rp pistol brass very thin wall in 38/357, but I haven't measured them across the spectrum. I would not be surprised to find that true in 45acp. Livelife has a chart for 9mm wall thickness that is probably a useful guide for most.I went through this exact same issue with a Tanfoglio Witness 45ACP. Would chamber factory perfectly fine. I then on suggestion from the CZ forum to try the Lee FCD and that fixed it. Then I started loading with R-P brass and that fixed it w/o the crimp die. From there I started casting my own lead bullets and sized them to .451". I now have zero chambering problems with that pistol.
I to believe casting your own is the solution
