Minute of angle (MOA) is the measurement(in fractions of degrees) of a ballistic round's deviation from its inital heading due to [[gravity]] and/or the effect of [[air resistance]] on [[velocity]].Informally known as a "Bullet's Trajectory" or "the rainbow effect". Long range weapons must account for this effect because a fired round falls at an [[exponential rate]] Weapons such as large caliber rifles use scopes with adjustments for [[distance]]and [[windage]] |
