The SAAMI pressures for the .32 S&W weren't listed in the latest pressure chart but it is less than the .32 S&W Long which is maximum 15,500 psi. The .32 ACP is 20,500 psi. The black powder loads are even way less than the .32 S&W Long so you could figure with .32 ACP you are probably DOUBLING the safe pressures the gun can stand. Sounds like a sure blow-up if you ask me. I would be loading that puppy with black powder meself. All pressures quoted are Piezzo, while CUP will be less.
