Never heard of those solving the problem but I'll damn sure try to put that in the back of my head in case anyone around here runs into it.
I coudl see the FA thing, I could realize the spring might help. Not sure how swapping the bolt could, BUT I don't discount suggestions. Glad I"ve never had the problem. Most likely don't quite see that in top line barrels I'd bet.
I to suspect cryo could help, but cost of that vs cost of the tube and not knowing if it would fix or not......
Now if I could just get back to working out the 1 and 2 groups from my 7x300..... always one flier in 3 shot work up groups... never consistent when... but talking bolt gun now and way OT...
