.416 Armor Piercing Explosive Round

The .416 caliber bullet is an armor piercing and explosive variant of the .416 (10.6mm) bullet designed by Everetti weapons manufacturer, Barrett Firearms.

Barrett .416
The Barrett .416 cartridge was designed by Pete Forras, who recently retired from Barrett. The bullet was designed using NACA low-supersonic-drag equations to design the shape. The cartridge was designed as an improvement to the .50 BMG cartridge, a common machine-gun and rifle cartridge. It is similar to a wildcatted .50 BMG case, shortened to 3.27 inches (83.06 mm) and necked down to accept a .416 caliber, 400-grain (26 g) projectile; It is however of proprietary dimension. Because the two cartridges, the .50 BMG and .416 Barrett, have identical base dimensions, all that is needed to convert a rifle to use one or the other cartridge is a relatively quick barrel swap. For some time, the only commercially-available rifle in this chambering was the single-shot Barrett Model 99. In August 2009, Zel Custom Manufacturing released the Tactilite .416 Barrett upper for AR-style rifles. Barrett now also chambers its semi-automatic M82A1 in .416 Barrett. The Armor Militant AM-250 Support Gun uses the .416 round. Armor Militant is working to provide the AM-777 Assault Rifle with a .416 caliber barrel.

Barrett/Armor Militant .416E
Armor Militant redesigned the .416, adding a reinforced bullet filled with high explosive material. Upon impact with a target, the bullet is designed to explode, sending both a small and fiery blast as well as shooting bullet shrapnel throughout the interior of the target. The new armor piercing round is designed to penetrate body armor and explode. Should the bullet pass through the body armor, it will explode inside the target, causing extensive damage to vital organs. Should the bullet not penetrate through, the bullet would explode in the body armor, causing damage to it, weakening the armor for future bullets to pass through with ease. The .416E is an already larger caliber round and it's power gives it penetration ability to most body armor. The bullet can be used in the Barrett M82A1, allowing it to be used as anti-material, penetrating armored vehicles and then exploding inside, sending shrapnel throughout the interior of the vehicle. Using the .416E in a machine gun like the Armor Militant AM-250, bullets can be fired in large numbers, causing immense damage to human targets either directly or targets inside of an armored vehicle. The AM-777 rifle would fire a smaller assault rifle variant of the .416E, making less powerful for armored vehicle penetration but enough power to cause damage to targets wearing body armor.
