Who ever told you that should study physics to gain a better understanding of ballistics. All rounds regardless of their mass are effected by gravity. The faster the velocity, the further the round will travel for the same amount of drop, that is it will have a flatter trajectory.

The mass of the round as well as it's velocity at impact will effect how much kinetic engergy the round will have.
