Benefit: If you have moved at least 10 feet toward your target since the start of your turn, your crossbow attacks deal an extra 1d6 points of precision damage against that target in this round. The damage increases to 2d6 on level 6.

In addition, reloading your crossbow does not provoke attacks of opportunity.

Special: This feat’s benefit doesn’t apply when you are mounted.
