I wish I could help or at least offer a suggestion but I can not.
My 308 bolt rifle is at constant risk of becoming a 6.5 creedmoor.....but.....the **** thing shoots really Really well, The barrel is only a small fraction of used, have enough premium loading components to burn the barrel out twice.
Still seriously at risk about three days a week................ Just a matter of time really..... before I cave and tear it down.
