[QUOTE="MagnumManiac, post: 2005898, member: 10755"] Race engines, which I build by the way, are a totally different environment to a rifle barrel. There is virtually zero stress applied to the threads of an action/barrel. Sure, there is torque applied by the rotation of the bullet and there is vibration. This is for milliseconds. A race engine has reciprocating masses that change direction, this is WHY head studs require lube under the washers, they actually move. Also, stretch used to determine pre-load on a rod bolt or head stud is because if it isn’t pre-loaded, it will shear if left without that preload. Stress risers are many on exposed threads, rolled threads, such as those employed by ARP, are far more reliable due to the rolling process compacting the steel rather than cutting and removing it, just like forging does the same thing. Anyway, there is no need to pre-load a barrel tenon in the way you’re thinking. Cheers. [/QUOTE]
