I use Warne QD rings on my heavy rifles. All of these rifles have good iron sights and sometimes when the jess is thick and the game has a bad attitude the scope is carried in a pocket. After replacing the scope on the rifle the crosshairs are still on.
Other rifles with clean barrels usually get Leupold rings and two piece bases, but there are several brands of rings & bases (all are steel) in my gun room. None of my rifles have picatinny rails for bases.
