Re: TPI, CPU, PSI

In reply to:
but that is the principle error
Agreed.
What's your take on the SAAMI spec's for the .357. It's 45,000 psi(crusher) or 35,000 psi(piezo). My guess is they just decided to de-rate the cartridge, for whatever reason. From some limited load book data, it appears that loads developed in CUP outperform those in piezo, suggesting that 45,000 CUP is indeed more pressure than 35,000 psi.
