AR bolts, unlike bolt action rifles, should be looked upon as expendables. The military uses a replacement cycle for M4 bolts of 5-10,000 rounds.
Grendel bolts, at least those available from AA, have been tested and upgraded from standard bolts and generally will last as long as the barrel. If you shoot hot loads, they may break, but the design is such that bolt breakage protects the rest of the rifle.
Several years ago I kept track of every broken bolt reported on ARF.com and here, and all but one of them came from handloaded ammunition.
You seek escape from pain. We seek the achievement of happiness. You exist for the sake of avoiding punishment. We exist for the sake of earning rewards. Threats will not make us function; fear is not our incentive. It is not death that we wish to avoid, but life that we wish to live. - John Galt
