I've never had an issue with Talley rings. Recently I purchased a pair of Warne QD for an old 1950 rifle. I prefer the Warne rings because I believe they are of better quality. Anyway, there is a method/trick to install vertical rings. First, install rings on scope and only tighten-up the bottom screw(s). Leave enough slack in the bottom screws that it will fit into the dovetails. Second, tighten the bottom screw(s). Third, adjust your scope for eye relief and reticle levelness. (don't use that crap thing - level bubble - it's nothing but a sales gimmick.
Fourth, tighten the top screw(s).........and voila!!!
If that does't work........then duct tape.
