So far I have used all the stuff suggested here, and all of it worked fine. At least half the time I use Talleys.
Have also used some other 30mm rings on various bases. They all worked fine too--except Weaver "tip off" 30mm rings don't work very well with heavy scopes on rifles that kick much. They do work fine on my my 6mm PPC, with a medium-weight 3-9x.
