I guess that made darned effective sniping rifles, too.
This from the Daisy museum site:
"Lest you dismiss the B.B. gun as kid stuff, the museum will remind you that during the Napoleanic Wars, the Austrian army maintained a regiment equipped with 0.44 caliber air rifles. This regiment had a higher rate of fire than a similar number of men equipped with muzzle loaders. They also didn't have to worry about misfires due to wet powder. They also could fire from concealment and remain hidden because their weapons made little noise and left no cloud of smoke. They didn't have to bother transporting quantities of explosive gunpowder or carry cannisters of it into battle, and their personal magazines were never accidentally detonated in battle by a stray spark. These air riflemen were so feared that Napolean ordered all those captured to be summarily executed."
