I have a friend who asked me to install his scope on his new 700 Remington in 7mm RUM. (Its a sporter barrel model, mounted on a lightweight synthetic stock - can you say OUCH!) I will probably go with a "turn-in" one piece base for this setup, along with an ocular pad to help buffer the dreaded "scope eye brow cut". The scope he chose for it is a Leupold Vari-X III, 3.5x10x50. He isn't into long range stuff, so I don't need sloping bases, or anything like that. I used the Burris Signature rings (the ones with the self aligning bushings)on my last scope mount and really liked them, and have had zero problems with them, but it was on a 22-250 with a lot less recoil. 1) Has anyone who has used the Burris Signature rings had them slip under recoil? I want to keep the scope as low as possible, maybe 1/8" above the barrel at the bell end (50mm, non AO) 2) What scope ring height should I use? Thanks!
