[QUOTE="BallisticsGuy, post: 1730781, member: 96226"] Easy to calculate to an approximation (this is calculating match barrel life and I've found the equations to turn out very reliable data up to .30cal bore diameter) but I think you'll be surprised at the result. I choose H4350 for the powder. 50gr @ 50000psi 1507 40gr @ 60000psi 1920 50gr @ 60000psi 1256 40gr @ 50000psi 2355 [/QUOTE]
