Re: Bolt Life?
Never had a Rem 700 bolt fail in any way, either in hunting, or in F Class type supported precision prone competitive shooting.
Ditto for Ruger 77MKII's, an M70 Post-64, Savage Model 10's.
I have managed to destroy probably over a half dozen ejector springs on a couple of Savage Model 10 Bolt heads. These were solely the result of blown primers, and I attribute them to operator misuse, rather than unacceptable parts failure.
When treated with reasonable wisdom, and operated with reasonable respect, factory parts will do the job they were designed to do long after anyone I know could reasonably fault them for their performance.
If I were planning to operate my equipment outside the limits of reasonable usage, my first choice for the upgrades would be GAP.
