Got a 700 rem in 300 win mag. Just picked up a new ziess 6.5x20-50 conquest. Never delt with ziess and was wondering what is the lowest ring size i could get away with using a 20moa base. I built the rifle to punch steel from 600 to 1000+yards. I have read that ziess does not have very good internal adjustment, but the glass is awsome. (which it is very clear.) If you need pics i can do. Any info will be much appreciated.
