[QUOTE="groper, post: 381435, member: 12550"] well i thought it would be a simple as 1 MOA (minute of angle = 1/60th degree) of rifle barrel angle movement = 1 MOA of movement on the target (= 1in @ 100yds)? Or 1 Milliradian of barrel angle change = 1m @ 1000m bullet impact change. why does it need to be anymore complicated than this? if your looking for what it means in terms of muzzle distance movement instead of barrel angle movment, simply scale it down to the barrel length. So if you move the muzzle by 1 MOA and say your barrel is 30in long. 1 MOA = 1in @ 100yds = 1in @ 3600inches = 30/3600 (barrel length divided by distance) = 0.0083 inches at muzzle = 1MOA = 1inch at 100yds.
