I am new to this long range shooting thing and have a question about the 20 moa base. I just bought a model 12 fv in 223 and plan to put a 6-20 I think it is Leupold scope that I already have on it. The longest range the club I belong to has is 600 yards. If I put a 20 moa base on this rifle will I still be able to zero the rifle at 100 yards? If I enjoy this type of shooting I may get another Model 12 FV in 6.5 Creedmore and put a Vortex Golden Eagle on it and possibly try shooting at other ranges at 1000 yards. Would the 20 moa base be what I would want for this rifle also and would I still be able to zero it at 100 yards?

I searched 20 moa base in this optics forum and didn't see the answer to this question I may not have gone down for enough.
