== M576 Buckshot ==
This type of grenade is loaded with 20 pellets of #3 plated buckshot (0.25" diameter, roughly 24 grains per pellet), effectively transforming the grenade launcher into a giant shotgun. These pellets are fired at a velocity of roughly 270 m/s (~885 ft/s), generating 57 Joule (42 ft-lbf) of energy per pellet. Although this is anemic in comparison to proper shotgun shells, each of these grenades contain 20 buckshot pellets, more than any size of shotgun shell in the Mazes. Shooting this ammunition type applies a '''[[FT]] -1''' effect.
Pain and Limb Damage listed on the table below are per projectile; multiply by the amount of projectiles that hit.
