Butcher (Borderlands 2)

The Butcher is a Shotgun manufactured by Hyperion. The Butcher can be obtained randomly from any suitable loot source, but has a higher chance to drop from human Badasses.

Special Weapon Effects
Very low pellet count. Greatly increased fire rate. Achieves maximum accuracy much more quickly than other Hyperion shotguns. Magazine randomly refills a random amount of ammo as it's fired, giving it a wildly variable magazine size in use. Fire rate increases under sustained fire.

Usage & Description
The Butcher is a very powerful shotgun. Despite having the lowest pellet count in the game (3 in most cases, 5 with Vertical Grip accessory), its exceptional fire rate, reverse recoil, and its unique ammo regeneration make up for this, and as such its damage potential is impressive. Under sustained fire, it gains and maintains excellent accuracy for much longer periods of time than most Hyperion shotguns. Because less time is spent reloading during a firefight, the Butcher possesses virtually unrivaled DPS.
