Mikecr, this was all new to me stuff, first trip to the range. Still not sure other than the manual was just printed wrong for that powder. Got some more loaded but haven't had time for a range trip yet.

I'm not telling you to do anything stupid, but max charge is obviously different for every rifle, seating depth, primer type, brass make, bullet etc... I have used 76.5grns of Imr4350 under a 178 hornady bthp touching the lands using winchester brass, CCI BR2s and a OAL of 3.531", I didn't go into an over pressure issue. Get data from 2 or 3 manuals to get a starting point, work up slowly, and find the max for "your" combo, not the books max. Be safe.

If the max charge is supposed to be at SAAMI max average specs of 52,000 CUP, how does one measure their charge's pressure without a pressure measuring system to find out what their load produces in their barrel?

I don't know of any visible inspection or physical measurement methods of fired cases is a way of assesing max pressure that's accurate.

No Bart there is not an exact method without a pressure barrel, however there must be some logic behind your smartass replys to everyone. I don't care who says what to me so, that said you're a ass, and no one is as wise as you. Since you're so damn good maybe you should check into working for Hodgdons, Sierra, Berger, etc... they need someone of your genius.

Wrong.

RSI - PressureTrace

It uses your barrel; no pressure test barrel needed.

How's this for a "smart ass" response to your statement based on ignorance?
