Yes there is.I personally have a marlin model 1894 cowboy ltd.that is chambered for the .45 colt cartridge.A few that come to mind is the rossi lever action carbine,the marlin model 1894,some Winchester model 1894 carbines,original Winchester model 1892 lever action carbines etc.With the revival of the cowboy action matches at gun ranges across the country gun makers are making more and more firearms that fire the .45 colt cartridge.
Several manufactures have made or continue to make them.

SCAR means Special Operations Forces (SOF) Combat Assault Rifle. A SMG fires pistol caliber ammo, the SCAR Light fires 5.56mm rifle ammo.
With the selector switch set to semiauto, the rifle fires one shot per pull of the trigger. This is in contrast to "burst" mode, where the rifle fires several shots per pull (usually 3) or "Full Auto", where the rifle fires until trigger is released.

In general. a rifle fires a single projectile that is designed to be spun by the grooves inside the gun barrel. A shotgun fires a much larger diameter shell. This is filled with multiple round lead pellets. The weight of all the pellets in one shell is usually greater than the weight of a rifle bullet, but they do not travel as fast, and are not meant to be spun when fired.
It's the caliber of the cartridge it fires.
An air rifle fires a projectile (usually a BB) using compressed air instead of an explosive charge.
