A musketeer character

A character with a Blunderbuss that does heavy close range damage like a shotgun, yet can be used at a distance to snipe enemies. Only downside, He has an ammo and reloading system. So after you fire the shot you have to reload for two seconds. His ability should be like a Caitlyn Ultimate from League of Legends, a brutal sniper shot that homes in one one target that you choose, but you cant move for the duration of the shot.
