The 10mm round is an ammunition type in Fallout 4.
Before the War, the powerful 10mm Automatic round was the standard ammunition for the Bureau of Alcohol, Drugs, Tobacco, Firearms and Lasers and other federal agencies, while the military was more reliant on experimental energy weapons (although it remained the round of choice for conventional pistols and submachine guns). The G brand of ammunition was one of the most popular, offering excellent centerfire cartridges for a variety of applications.
The basic 10mm Automatic round is a standard full metal jacket bullet: A soft metal core surrounded by a jacket made from tougher metal. This allows for higher muzzle velocities and greater damage, as well as increased performance against armor. The increased damage is reduced somewhat by the fact that the metal jacket limits the expansion, resulting in less kinetic energy transferred to the target.
