I have sent my beloved old Ithaca deerslayer to the factory to have a cantilevered rifled 24" barrel installed. So now my quest for a scope begins. I know most of my shots won't be beyond 100 yards but if the gun can do it I at least want the opportunity. I'm am looking at the Nikon slug hunter with the BDC reticle or the Leupold VX with SABR reticle. Both would be 3x - 9x X 40. Has anyone tried either or have a preference? They are very similar in cost and warranty.
