Re: grouping for 600yd whitetails ?????????
Most want to stay in or around 1/2moa. 1/2inch at 100 and 3 inches at 600yds. I always like to find the best group with the lowest extreme spread. Run them over a chrony to find your velocities of your loads. The difference between you lowest and highest is your extreme spread. Basically I am making sure of consistency.
