Yes with the proper loads this shotgun can be used to hunt anything even up to and including Bear "The Stoeger Model 3000 is a 3-inch 12-gauge Inertia Driven semi-automatic shotgun that handles loads up to 3-inch magnums without adjustment -- the perfect choice for waterfowl, wild turkey, or upland game birds. The heart of the M3000 is the proven Intertia Driven operating system: simple and efficient with only three moving parts in the bolt for lightning-fast reliable operation. Unlike older gas system guns, the M3000's Inertia Driven action is contained primarily within the receiver, giving the M3000 a better more centered balance and swing. With no propellant gas venting into the action, the M3000 shoots clean and stays clean longer.
The M3000 comes with either a 26- or 28-inch barrel, fitted with a ventilated, stepped rib and Fiber-optic front sight for quick target acquisition, even under low-light hunting conditions. The allow receiver is drilled and tapped to accommodate a Weaver-style scope base. All M3000's come supplied with three choke tubes (Extra-full turkey, Modified, and Improved-Cylinder), and a shim kit for drop and cast adjustment.
The M3000 is a rugged, solidly constructed and practical firearm that has been drilled and tapped to accomodate Weaver-style scope bases. For reliability and performance, no other semi-auto in its price range compares to the M3000, which will more than fulfill your hunting needs."

Mark,absolutely yes. Bird thru Bear will depend solely on your selected ammunition that can range from bird shot, buck shot or slugs. Match the load to your game and the shotgun is very versatile for a wide variety of game.
