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]], the [[BR75|BR75 Battle Rifle]], and the [[BR85 Heavy Barrel Service Rifle]]. While the round was designated as experimental around [[2525]], at some point between then and [[2558]], the "experimental" designation was dropped, becoming the M634 9.5×40mm HP-SAP.{{Ref/Reuse|waypoint}}

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 7.62×51mm 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]].

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]]. The round is intended for high-velocity and long-range marksmanship.
 
The M634 is likely the result of human inclinations towards increased size (leading to the 9.5 mm bullet) and technological manipulation (leading to the experimental propellant). The larger caliber is probably also required to increase stopping power and to defeat the advanced body armor of the Insurrectionists and the Covenant. At some point before 2558, the experimental identification of the M634 was removed, suggesting the round received formal adoption by the [[United Nations Space Command]].
 
The closest real-life counterpart of this round being the [[wikipedia:.375 SOCOM|.375 SOCOM]], which is a sized down version of the  [[wikipedia:.458 SOCOM|.458 SOCOM]], a cartridge designed in 2000. However, the .375 SOCOM was designed in 2013 after the battle rifle first premiered in ''Halo 2'', and interestingly shares its 9.5×40mm cartridge measurements.
