The '''12.7×40mm''' cartridge, also known as '''.50-caliber''',{{Ref/Reuse|SilentStorm3}} is a form of ammunition employed by the [[UNSC]]'s [[M6 series|M6 Personal Defense Weapon System]] line of handguns.<ref name="OSFM186">''[[Halo: Official Spartan Field Manual]]'', Page 186</ref>{{Ref/Note|The illustration of the 12.7×40mm round here features both the erroneous dimensions of and designation "12.7x30mm".

This page lists this designation as one related specifically to packaging, because there is no source that actually links it to an existent ammo type. However, it is possible that it is an alternate designation for SAP-HE ammunition itself, or potentially that it is even its own ammunition type that for reasons unknown shares its alphanumerical designation with the standard SAP-HE round. Due to the lack of mention of any SAP-HP ammo outside the in-game ammo packs, however, it is probable that this is an art error that has managed to transcend from one game to the next and persist over time. Due to the sheer number of re occurrences however, this is been debated.}}<ref>''[[Halo 3]]'', Magnum ammo pack</ref><ref>''[[Halo: Combat Evolved]]'', Pistol ammo pack</ref><ref>''[[Halo: Combat Evolved Anniversary]]'', Pistol ammo pack</ref><ref>''[[Halo 2]]'', Magnum ammo pack</ref><ref>''[[Halo 2: Anniversary]]'', Magnum ammo pack</ref> It was noted to have made the weapon that fired it almost as effective as an [[MA5 series|assault rifle]].<ref>''[[Halo: Silent Storm]]'', Chapter 15</ref> Its physical effects against vulnerable targets can be brutal,<ref>''[[Halo: Silent Storm]]'', Chapter 3</ref> particularly when the projectile impacts the target's skull,<ref>''[[Halo: The Flood]]'', Chapter 1</ref> making headshot-targeting with weapons firing this ammo an advisable tactic in combat with Covenant troops, who often possess resilient biology.<ref>''[[Halo: Combat Evolved Manual#Human Weapons|Halo: CE manual, Page 17, "M6D Pistol"]]''</ref> This ammo type is fed into [[M6 series|M6 series handguns]] via 6-,<ref name=ENC"321">''[[Halo Encyclopedia (2009 edition)|Halo Encyclopedia: The Definitive Guide to the Halo Universe (2011 edition)]]'', Page 321</ref> 8-,{{Ref/Reuse|OSFM186}} or 12-round detachable box magazines.<ref>''[[Halo: Combat Evolved]]'', Gameplay</ref>
