I could have a chance at getting a savage 90 (?) cheep in 250 savage. I was told the gun is in perfect shape, the only problem is, the rifleing was messed up while being transported in a truck. A tool made its way into the muzzle messing up the rifling to about 2 cm. My question, if I buy this gun, can I have 2 cm of the muzzle cut off with out effecting the gun?
