I'll break the trend of heavy duty/tactical style hardware and advocate something different. Slowly but surely I have installed Burris Signature rings on almost every rifle I own.
I have yet to see the scope slip in one of the Signatures rings and regularly shoot heavy loads in my 300 RUM and 338 RUM. I occasionally find a desire to swap scopes and have never seen a ring mark of any kind. 10moa - 20moa is easy to accomplish with the inserts provided and scope tubes can't be bent or bound by Signatures.
Just my 2 cents, even though I know this goes against the grain here.
