12.7x40mm
From Halopedia, the Halo wiki
The 12.7×40mm cartridge, also known as .50-caliber,[1] is a form of ammunition employed by the UNSC's M6 Personal Defense Weapon System line of handguns.[2][Note 1]
Overview
M6 series pistols, the weapons that fire this ammo, are noted to possess impressive range and stopping power due to its use.[3] As with many UNSC small arms ammunition types, however, the round has been observed to be somewhat inefficient against energy shielding.[4] There exists a distinct lack of variety in ammunition types of this cartridge available to soldiers in the field, something that the UNSC marines of E2-BAG/1/7 found strange given its high caliber.[5]
Variants
M225 SAP-HE
M225 12.7×40mm SAP-HE (semi-armor-piercing, high-explosive)[6] ammo (also known simply as “SAPHE”) is the standard-issue round for the M6-series.[2] The rounds are nickel-plated,[1] and are frequently distributed under the designation “M225 12.7×40mm SAP-HP” in 60-round packs.[note 1][7][8][9][10][11] It was noted to have made the weapon that fired it almost as effective as an assault rifle.[12] Its physical effects against vulnerable targets can be brutal,[13] particularly when the projectile impacts the target's skull,[14] making headshot-targeting with weapons firing this ammo an advisable tactic in combat with Covenant troops, who often possess resilient biology.[15] This ammo type is fed into M6 series handguns via 6-,[16] 8-,[2] or 12-round detachable box magazines.[17]

Notes
- ^ The illustration of the 12.7×40mm round here features both the erroneous dimensions of and designation "12.7x30mm". This is a common theme from sources of this period relating to the round, but has been overridden by more recent sources such as the Halo: Official Spartan Field Manual, Halo 4: The Essential Visual Guide, and the Halo Waypoint article on the Magnum. This image should not be taken as a reliable source, but remains broadly relevant.
