The Lewis And Clark Air Rifle

A friend of mine directed me to this video by the National Firearms Museum. This video explains how an air rifle carried on the Lewis & Clark expeditions was part of the crews “parlor trick”  introduction when encountering tribes of indians. The Girandoni repeating air rifle holds 26 .43 caliber round balls, is capable of punching a hole through a 1 inch thick pine board at 100 yards, and will can fire about 40 times before loosing muzzle velocity.

Where are the modern versions of this gun? Think of the money you’d save on ammo.
