416 BARRETT

The 416 Barrett (aka 10.4x83mm) was introduced in 2005 as an alternative to the 50 BMG. It is based on a shortened 50 BMG case that was additionally necked down to seat a .416 cal projectile; thanks to the two rounds’ identical base dimensions, converting a 50 BMG rifle to fire 416 Barrett ammo only requires swapping its barrel. Normally available with the same 398 grain projectile it was first introduced with.
