Thanks for all the replies, fellas. Looks like the Warren Rings are on the top thus far. I plan on putting at least three rings on the base/scope. It is a Leupold VX-3 scope on a MGM base and barrel and I believe I will have the room.
Offshore, here's a little food for thought. There is a Big difference between Warnes standard rings and their Tactical ones. I have 2 Tactical Warne Rings on my SSK Encore pistol in 500 S&W. I've put about 350 full load rounds through it. The scope ain't going anywhere
