I forgot to mention that I use the scope at the highest mag because it shows every little movement I make including my heartbeat which I learn to control the best I can. Of course, I'm a 1/2" MOA shooter at best but I'm a consistent 1/2"shooter. It takes many groups from 100-500 yds on various days under various conditions (weather, bench, tripod, prone, sitting, etc) with different loads and will pick the most consistent/repeatable combo which I will use for hunting.
I'm just an average man that has an above average addiction to hunting and I've come to accept that my guns can outshoot me.
