Anything with recoil at 6.5 JDJ levels or less, rifle or pistol, gets Weaver bases and 2 Burris Signature rings. Not for the recoil, but because the polymer ring inserts are self centering and put almost no lateral stress on the scope tube. Plus I've never had a scope slip in these rings. For my big boomers, I have SSK put on a T'SOB base,(about $55 without rings, plus return shipping), then add 2 or 3 Signature rings depending on recoil level. Just to see if they'd hold, I only put 2 on my Encore rifle in .375 H&H Magnum. Run about 20 rounds a month through it to keep my shooting muscles in shape. So far, no slippage.
