The HK MP7A1 is a select-fire pdw chambered in 4.6×30mm, built by HK in Germany. From its 180 mm (7.1 in) barrel, Fiocchi 4.6x30 H&K Full Metal Jacket (40 gr FMJ) leaves the muzzle at about 1900 fps (579 m/s). Zeroed at 50 m, the bullet drops 51 mm by 100 m with 284 J (209 ft-lb) left. At the muzzle that is enough to defeat Drywall, Plate Glass, Pine Wood and Brick, and not enough for AR500 Steel and Kevlar NIJ IIIA. It feeds from a 20-round magazine.
Computed by the BallisticEngine engine for this barrel length, zeroed at 50 m, 15 °C, sea level, no wind.
