PTP

Thanks for the replies everyone, we were a bit stuck but this gives us some solid threads to follow! This is extremely rough testing, and honestly we're trying to see where things break. Ideally we're trying to see of the system can handle most any market available ammunition, if I can overshoot +p+ and not expload then I'll call that a sucess.

Howdy, I'm wondering if anyone has some specific load data for getting a specific pressure high-pressure loads on 9mm. The actual performance of the round doesn't really matter, this is purely for stress testing in a controlled and secure environment. I'd like to reliably make rounds that can at least semi-accurately step-up to the proofing test pressure of 47000psi; but as no official data really goes above +P I figured maybe someone here would have their own. Also, if someone actually knows the proper equations to estimate pressures that would be incredible. While testing is done with practical instruments for obvious reasons, I assume there must be some roughly accurate calculus out there. Appreciate any and all assistance, thank you.
