[QUOTE="jwp475, post: 152182, member: 3776"] I just want to say, that with a custom built rifle that has been squared and trued with the lugs lapped in, that by the time you see sticky bolt lift that you are way over 60,000 psi probable close to 80. John Barnsess wrote an article about this and verified this with pressure epuipment. A factory chambering will usally show excessive presure signs way before a properly bolt custom rifle will.He also proved that if a reloader is shooting a much higer velocity than normal then the pressure is higher than normal.As long as you are useing the proper burn rate powder you can be certain that higher than normal velocity is also higher than normal pressure. In one rifle JB recorded nearly 80,000 psi belore traditional excessive pressure signs began to show up Widcat you continue to claim your velocity was without presure signs.Well if there were no pressure signs then how did the bullet get out of the barrel?
