I have one that is definatly toast. Received a bunch of take off barrels. Two Remington model 722s in 300 savage(one is a carbine?) and a Winchester model 70 in 264. Its a 22 inch FWT C.M. steel one. Looks perfect from the outside. However when you look at it through a bore scope, alligator skin galore in the throat! What do i do with it? I'm obviously keeping the hood and rear fold down sight but is the barrel finished?
