I need a scope for shooting anywhere from 100 yards to maybe 1,000. I shoot ground hogs out to 6 or 7 hundred and may try a 1,000 yard event. My main concern is very precise and repeatable clicks. Once I develop my drop chart, I want to have faith that the scope is repeating the clicks accurately. Clarity is the second concern. Considering the Leupold 6-18 or a Burris Signature or FullField 2. Any insight would really make the decision easier. Also, if you know of any cheap places to buy these scopes???
