I've used Talley lightweights for the past decade. Decided to try a pair of weaver bases and 30mm signature zee rings. Mounted them on a model 70 338 mag with a 3-9 SS. After about 6 rounds I noticed that the scope was slipping forward. Made sure all 8 of the ring screws were farmer snug, definitely tighter than I'm used to and ran about 15 more rounds through it. Still slipping. I'm not sure if the oil that came on the rings is adding a little to much lube to the plastic inserts or what. I'll clean any oil off and try it again.
