I was just messing around, reconfiguring my 264 lbc. Changed handguards taking the pink off since the girls have little interest and swapping out scopes. Zeroing it in, after the third shot the fourth didn't fire. I checked and the bolt wouldn't go into battery. Further investigation showed a broken lug on the bolt, and part of the piece was in the barrel extension and didn't allow the bolt to lock up. Probably a good thing.
This bolt has over 1k rounds for sure and how many more I don't know. It's from Surplus Ammo where the barrel came from. I don't know who they source bolts from.
Last fall I had a Radical bolt fail on the 243 lbc. That one with 1400 rounds maybe. That was a cheapy but I thought this one was better. Guess not. I have one bolt left between the two uppers, now I have to find some more or ditch these accurate barrels when the last bolt fails lol.
I read where Greg is using Rguns bolts? They are carp 158, is that better? I really didn't think my loads are hot, at the top of book but not over. Using adjustable gas to not over stress things.
The Grendel guys say broken bolts are not prevalent, but I either bought two inferior bolts or it's a design issue. At this point I can't recommend this line of cartridges any more even though it's phenomenal imo, esp the 243. I might try AR15performance barrel with the re-design 750 bolt.
