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 similar if not higher muzzle velocity then the [[7.62x51 NATO|7.62x51mm NATO]] while using a smaller cartridge; the M634 X-HP-SAP effectively packs a larger "punch" in a shorter casing. It is also semi-armor-piercing, meaning that is 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 [[M7/Caseless Submachine Gun]].
