I purchased this barrel thinking I would use it for a .308 build decide to go with 260. Don't know much about the barrel. It is a new shilen and is threaded for a remington action I actually figure it is this barrel Shilen Match Grade Barrel Remington 700 308 Winchester 1 10 Twist . The barrel is remington varmint contour stainless steel and has already been crowned. It is 26" and has .308, S.S, 107 and V.F. on the chamber end. It does have a chamber but it is not finished because one of my .308 will not drop. I am definitely not a gunsmith but I will take what ever measurements someone wants. 275 shipped or trade for 260 or 6.5 barrel.
