rate of fire
5 (15 pellets, 5 pellets alt fire)
Use Bucky's primary fire for close-ranged engagements and its alternate fire for mid-ranged engagements (similar to Roadhog from Overwatch).
The Bucky, along with all other shotguns, allows you to shoot with less of a penalty while jumping than other weapons, however the alternate fire suffers heavily from jumping.
