Instant Return Feat 16
Source Pathfinder Guns & Gears
Trigger An enemy misses you with a ranged attack using a type of ammunition appropriate to your weapon (a bullet if you're wielding a firearm).
Requirements You're wielding an unloaded firearm or crossbow.
With a single fluid gesture, you catch a projectile out of the air, load it in your weapon, and shoot it back at the attacker. Interact to load the projectile into your weapon, then make a Strike with the required weapon against the triggering opponent. Since you're using the foe's ammunition, this Strike applies any special effects that ammunition would have (for instance, if it was Explosive Ammunition, it would explode in a burst of fire if your Strike hits).
