I have two large shank savage barrels I am looking to trade. 204 Ruger large Shank Savage Take off. Unknown round count, i took on trade. It still shoots good. 0.5"-.075" consistently. 6mmbr barrel 1-12" twist. 800+- rounds. Will shoot sub 1/2" easily. I am looking for a fast twist 22 or 6mm barrel on trade, any caliber.
