== 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.

This type of grenade is strictly intended for practice and training. It fires an inert projectile at low velocities, which releases orange smoke upon hitting the target, or automatically after 10 seconds.
M382 practice grenades are '''not''' available in retail; they are exclusively found at shooting ranges. Should such ammunition somehow leave If the confines of training, circumstances call for it , this grenade type can be used as a weapon, albeit with mediocre effectiveness, due to its blunt, non-explosive nature and its low velocity.
