The round was designed as a competitor to the 5.7 x 28 mm round developed by Fabrique Nationale. In head-to-head comparison of the two rounds, 4.6 x 30 mm fired out of the MP7 is slower and offers slightly shorter range and reduced terminal ballistics than the 5.7 x 28 mm fired out of the PS90. SS195LF, with a 28 grain projectile, fired out of the PS90 can achieve muzzle velocities of approximately 2500 ft/s. Ballistic gelatin is a solution of pork gelatin powder in water. ... ...

The 4.6mm caliber has been criticized for its supposedly low terminal effectiveness, but in real use this is not a problem. Because of its accuracy and low recoil the 4.6mm cartridge is deadly in the hands of any competent shooter.

The latest version ("Ultimate Combat") uses a 2g steel projectile at the same velocity, giving it a significant edge both in terminal effectiveness and perforation over the 5.7 x 28 mm cartridge.
