Thanks for posting this - always useful to see and learn from failures. For a gun and cartridge supposedly considered for military adoption, it damned well better be able to keep up with that rate of fire. I've taken my Grendel 3-gun shooting, and there are video's from Grendel promoters showing full-auto fire. At 52,000 PSI rating, it should be able to take that all day.
For what it's worth, Wolf broke my Grendel extractor last week, on my PSA rig - at just 600 rounds in. 1st shot of the day. That rig has a carbine gas system. And carbine gas systems see a harder life in general. Combine that with Wolf steel, which is loaded on the high end of that (I think), and is steel, and things see a harder life. Still, it shouldn't have broke, and hopefully they will RMA that bolt for you.
In the meantime, I did find one place that has reasonably priced bolts and extractors. PSA supposedly will replace my broken extractor, but haven't yet. So I picked up a couple from Black Rifle Arms, which were under $20. They are selling bolts for $70. For all I know, it's junk; but heck - can't be any worse than the part that broke already.
