Don't know your rifle, or barrel, but Armalite makes a super break used on their .308's, .300WM, .338 LM, and .50. You MIGHT be able to get one from them and hav ea good gunsmith put it on your barrel. I don't know how possible that is, but might be looking into. I have the Armalite in .338 Lapua Mag, and with the break, I can shoot it all day. Recoils like a 243. I have had several 80 -100 rnd days on the range with it with no recoil issues, Though the sound, now that is still an issue as stated above.
