Birdshot
Shotgun ammunition loaded with many small pellets.
Birdshot is shotgun ammo with many small spherical pellets — sized for upland birds, waterfowl, and small game. Pellet sizes range from #9 (very small) to BB (large) within the birdshot category. Pellets spread as they leave the muzzle; the wider the spread, the easier to hit a moving target but the less energy each pellet carries.
