The 4.6×30mm (designated as the 4,6 × 30 by the C.I.P.) cartridge is a small-caliber, high-velocity, smokeless powder, rebated rim, bottlenecked centerfire cartridge designed for personal defense weapons (PDW) developed by German armament manufacturer Heckler & Koch (HK) in 1999. It was designed primarily for the MP7 personal defense weapon (PDW) to minimize weight and recoil while increasing penetration of body armor. It features a bottlenecked case and a pointed, steel-core, brass-jacketed bullet.

4.6×30mm maximum C.I.P. cartridge dimensions; all sizes in millimeters (mm).
Americans define the shoulder angle at alpha/2 ≈ 22 degrees. The common rifling twist rate for this cartridge is 160 mm (1 in 6.3 in), 6 grooves, Ø lands = 4.52 mm, Ø grooves = 4.65 mm, land width = 1.21 mm and the primer type is small rifle.
In C.I.P. (Commission Internationale Permanente pour l’Epreuve des Armes à Feu Portatives) regulated countries every rimless rifle cartridge combo has to be proofed at 125% of this maximum C.I.P. pressure to certify for sale to consumers. This means that 4.6×30mm chambered arms in C.I.P.-regulated countries are currently (2018) proof tested at 500.00 MPa (72,519 psi) PE piezo pressure.
The Belgian 5.7×28mm cartridge introduced in 1993 is probably the closest currently available ballistic twin of the 4.6×30mm.
The 4.6×30mm ammunition is produced by RUAG Ammotec, Fiocchi and BAE Systems.

The 4.6×30 Ammo cartridge was introduced in 1999 as a competitor to FN Herstal’s 5.7×28mm cartridge Heckler & Koch started the development of a semi-automatic handgun for their 4.6×30mm PDW cartridge, but Heckler & Koch cancelled the Ultimate Combat Pistol (UCP) at the prototype stage.

Compared to standard intermediate cartridges one can carry more 4.6×30mm ammunition due to the lower weight and relative small dimensions of the cartridge. Also, due to the lower weight of the bullet, aiming in rapid fire is much easier as recoil depends much on the weight of the bullet. CRISAT testing shows that because of the smaller diameter and high projectile velocity of the round, body armor penetration is higher than that of traditional handgun projectiles.
