[QUOTE="CliffM, post: 951729, member: 11533"] Is there a muzzle pressure that the minimum wall thickness is based on. Out of curiosity I compared my 6.5 Sherman loads to 6.5x47 loads with different barrel lengths and powder burn rates. the calculated results spanned from 7000-17000psi at the muzzle, that is quite a large range IMO to arrive at a generic safe diameter per caliber.
