I am curious what would be considered good shooting from the prone position. I am shooting a sporter weight (9.5# with scope) 300 Win Mag with my Harris bipod. I am not using a rear bag. I have tried one and overall it does not seem to help. Anyway today I shot 9 shots (3 groups of 3 shots with cooling in between) at 400 yards with the 180 Swift Scirocco. 6 shots were in 4.15", 8 shots were in 6" and all 9 shots were in 8.4". So 8 out of the 9 were in 1.5 MOA from field conditions. To me that seems pretty good. Certainly good enough for taking out a deer at that range. The main question I have is if you can shoot 0.5" 3 shot groups from a bench at 100 yards what could you do prone for 9 shots at 400 yards? Can many of you keep 9 shots in 1 MOA or less from prone at 400 yards? Just wondering how I am doing. Thanks, Rufous.
