I have a savage 300 WSM and my scope all of a sudden started to twist. This canted my croos-hairs I kept loosing and releveling my scope. After this deer season I took off my scope and discovered that my scope has major grooves in the case. Ruined a 500.00 scope I suspect that my rings were the issue.. I know I went the cheaper route and bought alum rings. I am looking for a new scope but am having issues as too what type or style of ring to get. I would appreciate any and all suggestions... By the way I am new to this forum but so far I am impressed by the knowlege you all have. thanks and have a great day.
