From a previous post by Bill Alexander regarding Grendel bolt design:

Bill Alexander Wrote:The change of 0.011" of depth of the bolt recess (3 sheets of writing paper) has significantly less bearing upon the life of the bolt than surface finish, let alone the geometry. What it will adversely effect is the extractor strength. The Grendel bolt design is not a simple opening up of the 5.56 bolt as typified by what is now referred to as the 7.62x39 bolt. The bolt is a balance of the extractor and the bolt geometry with the steel type used and the heat treatment. The pressure limit was set to 50,000 psi to provide a wide margin of error and also allow for an exceptional cyclic life. It also balances the recoil generated with weapon controllability in a platform weight conducive to the small platform the cartridge was intended to fit.
