You only gain the benefit of this feat when
wielding a weapon with which you are proficient.
The time required to reload a single shot weapon, like
a crossbow, is reduced to a free action. This permits you
to fire that weapon as many times as you have attacks
.
Reloading a heavy single shot weapon is a move action.
Reloading a firearm or energy weapon with an
ammunition pod, power cell, box magazine, or speed
loader is a free action. Reloading a revolver without a
speed loader, or reloading any firearm with an internal
magazine, is a move action.
