I have had my S&W 460 for about a year now. Before last deer season I purchased the Warne mount with Warne rings and a Burris 2-7x32 scope. I'm having problems with the scope. I can only use power 2-4 anything higher and I can't get around the parallax. The scope is as far forward as it will go. I'm looking at trading this scope for the Burris XTS-135. My shots will be under 100yards, so the lack of magnification shouldn't hurt. My question is, the XTS-135 only has room for 1 ring but comes with a large ring with 6 screws, will this work or will I experience movement?
