I have a set of Burris Signature rings,and a offset set of inserts for them. I'm wanting to get 20MOA for long range shooting. I've put the +20 insert on the bottom of the rear scope ring,with the -20 insert on top of it. I have the front inserts installed with a set of 0 inserts. It seems to angle the scope,and makes the rear a little too high. My question is,could I use a +10 insert on the rear with a -10 insert on top,and a -10 insert on the front with a +10 insert on top in the front ring for the same +20 effect,rear 10 higher,and front 10 lower)? I would like to get the scope a little lower for a better cheek weld. Will this have the same effect as just using the +20 in the rear ring? Thanks Ron
