M645 FTP-HE

The M645 Ferric-Tungsten Projectile - High Explosive is a 16mm x 65mm slug round used by Acheron Security's ARC-920 railgun.

Overview
The M645, contained in a rectangular casing, is loaded into the railgun's internal magazine through a topside well. The slug contains a high-explosive charge to aid in armor penetration. Coupled with the kinetic force imparted by the weapon's high muzzle velocity, the M645 can penetrate both hard and soft targets; ideally it is to be used against well-armored personnel. The slug is fired with such tremendous speed that it is enveloped by plasma while in flight.
