Haven't broke one yet and don't know anyone who has.
Seen some on the grendel Facebook page and 99% percent of the time it was either handloads way over pressure, a highly overgassed rifle that was the cause of the issue.
Lapp the upper and keep the rifle properly gassed for a 3 to 3:30 ejection pattern don't try to turn your grendel into a creedmoor with 60k handloads, buy a known high quality bolt and bolt breakage won't be a problem.
All bolts will break no matter what caliber the bullet in the end of the case.
