" …*Only out to a certain distance till the heavier projectile slows down before the lighter one. Once that happens, I don't know? But then again, out of the same air gun, wouldn't a lighter projectile always move faster?"*

If I'm not mistaken, at a certain distance, the heavier pellet would overtake the lighter pellet in both speed and range/distance (also carrying greater energy down range), due its ability to overcome the wind resistance better than the lighter pellet.

See: ballistic coefficient.

Heavier projectiles generally have greater "ballistic coefficient" than lighter projectiles.
