'''M634 Experimental High-Powered Semi-Armor-Piercing''' (abbreviated '''M634 X-HP-SAP''') ammunition is a type of rifle projectile that is made specifically for the [[Battle Rifle|BR55 Battle Rifle series]]. Its metric dimensions are 9.5x40mm, compared to the [[M118 7.62x51mm Full Metal Jacket Armor-Piercing]] [[rounds]] used in the [[MA5 Series]] of UNSC assault rifles. It was introduced into the [[UNSC Marine Corps]] along with the [[BR55 Battle Rifle]].

A M634 9.5x40mm KURZ from The Art of Halo 3.

M634 Experimental High-Powered Semi-Armor-Piercing, abbreviated as M634 X-HP-SAP and also known as the 9.5x40mm KURZ,[1][note 1] is a 9.5x40mm rifle cartridge made specifically for the BR55 series and BR85 series.[2]

Overview

The M634 X-HP-SAP was developed in conjunction with the prototype XBR55 Battle Rifle. As an experimental round, its use is only limited to the BR55 Battle Rifle, the BR55 Heavy Barrel Service Rifle, and the BR85 Heavy Barrel Service Rifle.

Performance-wise, this round is accurate enough that the 2x scope on the Battle Rifle is useful. Even when fired in three-shot bursts, the round produces little recoil resulting in very little muzzle lift. It is more effective against both shielded and unshielded Covenant personnel than the M118 7.62x51mm round, as the increased accuracy leads to an increased kinetic energy of the round leads to faster shield depletion and increased damage to unshielded enemies. Overall, the M634 X-HP-SAP round provides good accuracy, controllability, and effectiveness against all personnel.

Properties

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 M118 7.62x51mm round while using a smaller cartridge. It is also semi-armor-piercing, meaning that it mixes the properties of an 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 SAP-HE used in the M6 Series.

Trivia

Unlike most ammunition types in the Halo games, this is not a real-life ammo type, the closest comparison being the 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. The M634 is likely the result of the human inclinations towards bigger things (leading to the 9.5 mm bullet) and technological manipulation (leading to the experimental propellant). It's also possible the large caliber, while overkill by current standards, is required to defeat the advanced body armour of the Insurrectionists and later the Covenant.
