I own a VERY CLEAN, LIKE NEW, Savage Sporter 25-20 serial #93482 . I have located 500 new cases and I am waiting for Hornaday to make a run of bullets (November). My question is the barrel has two screws center top, 1.5 inches and 2.5 inches from the rear end of the barrel. Can these be used for a scope mount and if so can you tell me which one??? Thanks Joe
