I have a 16" standard ar upper and am looking at a new 22" upper to mount a longer range scope on for coyote hunting. I looked up the ballistics and I shouldn't be shooting more than 600 yards. Maybe 700 max. And I know the .204 is a flatter round but the .223 is heavier and will be less resistant to wind. What are y'all experiences with either or both rounds and which do you prefer?
