I have a 338/378 barrel off a Weatherby, with muzzle break. I tried to sell it but it won't find a new home. Is there an action other than Weatherby this would work on. I hate to see it as a tomato stake.

the head space is not going to be correct and the tenon may be short or long but the thread size is the same as a Rem 700

That is If it's off a Mk V
