10mm

10mm is an ammunition type found in Fallout, Fallout 2 and Fallout 3. 10mm ammo ranks as the most common Small Guns ammunition in all three games. In Fallout Tactics and the canceled Van Buren it was replaced by 9mm ammo.

Background
Before the War, 10mm was the standard ammo for the Bureau of Alcohol, Drugs, Tobacco, Firearms and Lasers, while the military was more reliant on experimental energy weapons.

Behind the scenes

 * I picked 10mm since it wasn't popular, had been tested by the FBI at one point (and found lacking), but it was basically a gun nut (which I am one) kind of round. .45 might have made more sense, but I was looking for something with a little twist. - Chris Taylor
