You might want to try one of these.

Pretty cheap and a lot of guys find it tightens up their groups considerably. Although all the advice about having all the screws (stock/bases/rings) torqued to spec is right on the money. $60 toward a decent torque screwdriver is a great investment.

It drives me nuts the way so many of the well known gun stores will mount a scope "by feel"... "I've been doing it this way for twenty years" they'll tell you. Well how many of those rifles have they tried to go out and shoot with? Thus endeth the rant...
