I like Leupold's Dual Dovetail mounts very much and have several sets. I bought my first set for a 340 that kept shearing the windage screw on the STD's close to 30 years ago now. My only complaint with them is that is you swap rifles and scopes a bit as I have been prone to do, the dovetails will wear out and become loose to the point the rings will move in them. Not a great thing, so I switched to PRW's which are strong nd easy to swap, but heavy. About 3 or 4 years ago I tried NEAR and have believe them to be excellent.
