Found out a match this weekend will be shooting 300yrd reduced f-class target. I have some friends that are telling me the reduced size target is harder than the regular targets. I don't understand this. If the 10 is 1 moa at 300 or 600. It would seem that the 600 would be more dificult with the additional wind. Help me understand why 1 moa at 300 would be tougher than at 600??
