Depends on:
Gas system length/barrel length
Gas port diameter
Loads used
Round count compressed in short time or spread out over long time
Suppressed without gas choking
Bolt alloy, processes, and QC
I've personally broken bolts on 5.56 CLGS blasters running very tortuous high volume sessions, but the bolts broke after 10,000 rounds of that. Had those bolts been made by Diameco in Canada or LMT enhanced, I doubt it would have happened.
I was going through all my Grendel brass recently and forgot how much of it I have. I let my wife pack up a lot of the boxes of it and she informed me I don't need to be buying any reloading components anymore.
Given the weight and volume of boxes full of Grendel brass, and the fact that a lot of it is into multiple firings (I found a ton of Lapua brass), I can only guesstimate how many thousands of rounds of Grendel I have fired through my various 6.5 Grendel AR15s.
As soon as I break something, I'll let everyone know.
Most of my Grendel shooting will be suppressed looking into the future, which can be harder on bolts if you don't manage the gas system well.
I'm using Bootleg carriers to choke the gas down to the most restrictive setting on them when shooting suppressed.
