[QUOTE="LouBoyd, post: 534226, member: 9253"] The older 1" Burris Signature series scope had a very small range of vertical adjustment. I don't know the exact model you have, but I had one wich ddin't have +/- 20 moa of adjustment. it also had target knobs where the number of clicks didn't match the number of makrings per revolution. (60 vs 56). That got real confusing. My advice would be to get a different scope. Even the $200 Burris 10x40 mil-do0t 3200 series scopes have about 90 MOA of vertical adjustemtn. The Leupold Mk 4 M1 16x40 has 140 moa of vertical adjustment, more than is needed for most cartridges which will reach 2000 yards supersonic. Before you buy a scope or a base run a ballistics program on the ammo you plan to shoot. I don't want any scope on my rifles which won't zero from 25 yards to whatever the maximum supersonic range of the bullet is. Also subsonic cartridges like the 300 Whisper and 300 BLK need lots of vertical elevation adjustment if used to their maximum effective range. As rule of thumb don't used a base with more than half the moa of the adjustment range of your scope. I leave at least 10 MOA so the scope never bottoms out.. That assumes the scope is symetrical. Scope knobs don't have to be symetrical. Not all scopes need tapered bases. For example in the Horus falcon the reticle is already offset by 20 MOA. [/QUOTE]
