I had a problem with Warne rings when used with standard Weaver bases. The recoil bent the side tab on the recoil cross bolt. The replacements worked fine when used with Warne bases that allowed full width contact with the base slot. The Weavers only have contact on the sides of the slot. I have also had good luck with the Leupold QRWs when used with any Weaver style base. The windage adjustment feature on other systems can help you deal with the base mounting holes not being true with the axis of the bore. If that is not a problem I would avoid them. The Weaver style mounting with clamping from one side allows you to maintain a secure zero after taking it off and putting it back on since the rings have a "home" on the base, unlike other systems (Millett for example). If your gun has the cantilever base, I would recommend the Leupold PRW since quick removal is not necessary (no irons). and there are no levers in the way.
