10mm is an ammunition type found in Fallout, Fallout 2, Fallout 3, Fallout: New Vegas, Fallout 4, and Van Buren.


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.[1]

Behind the scenesEdit

I picked 10mm since it wasn't popular, had been tested by the FBI at one point (and it was too much for agents to handle), 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.
