[QUOTE="Bart B, post: 103499, member: 5302"] Forget doing anything to make the receiver or even the barrel stronger to handle high pressure loads safely. Your rifle will easily handle loads producing up to about 130,000 psi. They all will do that. The problem doesn't exist with the steel in the rifle. The problem is brass cases. Nobody makes cartridge cases that handle pressures higher than about 70,000 psi. That's the point they start extruding back into the bolt face through the ejector hole/slot and expanding primer pockets such that they won't hold primers any more. One solution is to have some high quality steel cases made that will withstand the high pressures you want. These cases won't be able to be reloaded, but at least you'll reduce the chance of having a case rupture and let high pressure gas blow back into your face and ruin your day. A better one is to back your loads off or use a larger cartridge case big enough to get the muzzle velocity you think you need. To answer you question: Yes, your 'smith might be able to make some steel cases for you to use......once, then throw them away. [/QUOTE]
