7.62x37mm Musang

The 7.62x37mm Musang is an assault rifle round developed and manufactured in the Philippines. The round's case is derived from the 5.56x45 mm NATO, but necked-up to accept a 250 gr bullet intended for subsonic speeds. The new cartridge was developed in the context of Philippines' Night Fighting Weapon System.

The 7.62x37mm Musang round is unrelated to the Soviet 7.62x39mm M43 round.
