Thus Spake Zargrabowski/ParryBullets

>>>Even if the Charm is 'Reflexive,' usually you don't hear the gunshot until after the bullet has passed through you. Yet, you can't really activate the Charm before the attack, especially if you're standing there waiting for him to pull the trigger but don't know exactly when he will. That's the scenario I was picturing.<<<

You have some unexamined baggage there about guns, and possibly haven't read enough kung fu epics. In Wing Shing-Ma's "Storm Riders", people have multi-page coversations while arrows race toward them. Mere bullets wouldn't be any more dangerous to an Exalt than any other attack. It's certainly easier to avoid than the Death of Obsidian Butterflies. You'd either need an epic rifle or a supernatural sniper.
