Testing some loads out today,groups were large ,check things and my scope wiggled like jello . Standard Leupold rings ,seams the bases are solid,but where the front ring cams into the base is where there was significant movement. . So I have some Burris Tactical rings,but they need picatinny rail . So what is the fix ? This is a WBY Accumark . What mounts and rings are guys mounting scopes 338 Lupua mag rifles ?
