It works like range increments in dungeons and dragons. For say, a dagger, the range increment of throwing it would be 10 feet. For every 10 feet of distance between you and your target, you do -2 damage. A target at 20 feet would take (20/10)2 = 4 less damage from being struck. Most daggers do 1d4 damage, so even if you roll a 4 it harmlessly bounces away! High velocity ammo is like the ranged weapon mastery feat; with this feat the dagger's range increment becomes 30 feet- and now a target at 20 feet takes full damage, where it took no damage before. You also get a bonus to hit.
