Everyone has favorites, I like Weaver Grand Slam bases and Leupold quick release rings.(both all steel) I have used them on heavy hitters with no problems. I like the quick release because I can remove the scope and use open sights or use a second scope if needed that is pre-zeroed (set-up ahead of time with same type rings and zero) These rings return to zero or very close. As mention before locktite everything. The Ruger rings are also very good if you get Ruger type bases.
