Effects of Bolt Locking Up In The Barrel

[Denver Steve]

There have been other bolt actions tested that have survived that pressure. The H.P. White laboratories tested the Schultz & Larsen action (used in their M54J, M60, M65, M68DL rifles) in the 1960s, and it withstood 129,000 PSI pressure. The Fortner system used in the Heym SR30 has been tested to 110,000 PSI without any problems. The Blaser R8, with its 14-lug radial collet lockup was tested at the DEVA Association laboratory in Germany and has withstood 210,000 PSI pressure.

From my understanding it is very similar to the blaser, but more are for bolt lock up. They proofed mine with ammo shot at 78,000psi at the factory.

Try getting a stainless barrel from S&L.

Yes, I'm guessing that they don't provide stainless because the barrel steel has to be hard enough, or hardened to the point, to handle the locking lugs and the lockup in the barrel along with the stresses in firing--which would require harder steel than is normally the case with stainless. S&L do, however, have a number of barrel options--straight-fluted, spiral-fluted, octagonal, octagonal-fluted.

That is the reason, at least I was told that in their factory however in our parts of the world stainless barrels are important. Many don't buy S&L because of that.

Didn't the bolt on the Remington 710 lock up into the pressed on barrel? Or am i having a senior's moment?
