Unknown Armies:Firearms damage

Firearms damage is identical to the successful attack roll—a roll of 45 does 45 wound points of damage. The higher your skill, the more damage you can do because you're shooting more accurately and you're hitting parts of the body that are more vulnerable. But your skill also serves as a limit on how much damage you can do. If you have a firearms skill of 40, you usually cannot do 70 points of damage in a single gunshot.

There is another limitation on your damage result: different calivers of firearms have different maximum amounts of damage they can dish out. If your successful attack roll is higher than the maximum damage for the firearm you're using, the damage you do drops to the maximum for that firearm.

Crits do maximum damage for that firearm—even if the maximum damage is higher than your Firearms skill rating.

Fumbles cause your weapon to jam or misfire. Semi-automatic and full-auto firearms jam and all others misfire. If it's a jam, you have to spend a round and make a successful firearms skill check to clear the weapon before it works again. If you fail the check then you can keep trying, but each attempt takes one round. If it's a misfire, nothing happens this round but next round you can fire again normally; mark off that bullet as a dud.

Matches have no effect on firearms damage.
