M634 Experimental High-Powered Semi-Armor-Piercing: Difference between revisions

As designated in its name, the M634 X-HP-SAP is an experimental round. It uses a special propellant that allows it to achieve a higher muzzle velocity than the [[7.62x51mm NATO]] while using a smaller cartridge. It is also semi-armor-piercing, meaning that it mixes the properties of an [[Armor Piercing Rounds|armor-piercing round]] with the properties of another type of round. The second type is unknown, though it is most likely similar to the [[M225 Semi-Armor-Piercing High-Explosive]] used in the [[M6 Series]].

Unlike most ammunition types in the Halo games, this is not a real-life ammo type, the closest comparison being the [[wikipedia:9x39mm|9x39mm]] special purpose round. Designed in the Soviet Union, this round was designed to defeat body armor at ranges closer than 100 meters, and be subsonic, so it can be easily used in suppressed firearms. In fact, most weapons firing it have an ''integrated'' silencer.
