I am looking at a Savage Mark 1 at a pawnshop. It appears to have a two groove barrel in good shape. How does the two groove barrels handle cast bullets? I am having a hard time getting the owner to negotiate on price. He is holding at $265 plus tax. This seems a little high to me. Any thoughts? I already have two Mark 1s, why do I need another? Someone please help me find a reason to walk away from this rifle!!!
