A very large caliber caseless magnum cartridge of cylindrical construction, it is a chemrail type round intended for use with dual stage weapons that employ a conventional chemical propellant paired with a second EM acceleration stage. In this case via a magnetic sabot sledded once the projectile exits the chamber. It is primarily used in the RP-44V 'Verk' Chem-rail Revolver, however various other platforms have developed modification kits to allow its use.

• In Service - 954 N.C.C.
• Used By - Colonial Pact Trade Alliance
• Type - Semi-Saboted Asynchronous Linear Projectile Cartridge (SSALPC)
• Projectile Diameter - 13.5 mm (0.531 in)
• Projectile Length - 35 mm (1.37 in)

A 404 grain cartridge with a full copper jacketed depleted uranium projectile with a specific deformation profile, it is the standard and most common variety of 531 Magnum ammunition.

• Damage Rating - Tier 2 Medium Anti-Personnel
• Cartridge Dimensions - 13.5×35 mm
• Damage Description - This cartridge employs the simple brute force method using its large size and velocity out of most Pact firearms to simply shatter its way through a target. Primarily designed for general use it has capabilities against both lightly armored targets and 'soft' targets. The first causing some deformation of the round with a grave potential to inflict harm even if penetration is not achieved, however if the round penetrates the targets armor the resulting deformation of the projectile can cause massive soft tissue damage. If used against an unarmored or xenoform target the results are outright brutal with massive damage to soft tissue and bone caused by the rounds passage.
• Recoil - Moderate (On par with a 44 magnum of average load out of a six inch barrel.)
• Firing Method - Electrically Primed

A 440 grain cartridge with a copper semi-jacketed hollow point lead projectile with a preformed expansion pattern.

• Damage Rating - Tier 2 Medium Anti-Personnel
• Cartridge Dimensions - 13.5×35 mm
• Damage Description - A low penetration hollow point projectile intended for use against soft targets or xenoforms, it does have some performance against soft lightweight body armor usually causing brute impact kinetic damage. It employs a precut projectile with a standardized expansion pattern after impact and is capable of causing massive internal damage to its target. (Half inch entry hole…. beach ball sized exit wound.)
• Recoil - Moderate (On par with a 44 magnum of average load out of a six inch barrel.)
• Firing Method - Electrically Primed

A 460 grain cartridge with a fully jacketed explosive payload consisting of a high temperature explosive incendiary compound at the tip designed to explode on impact and burn through or degrade armor. An even higher temperature compound with a high density is then ignited and carried through the weakened point in the armor, burning and damaging anything on the other side.

• Damage Rating - Tier 4 Light Anti-Armor
• Cartridge Dimensions - 13.5×35 mm
• Damage Description - A high heat semi-kinetic chemical explosive round with an initial explosive incendiary tip and a higher density long burning incendiary filler.
• Recoil - Moderate (On par with a 44 magnum of average load out of a six inch barrel.)
• Firing Method - Electrically Primed
