BB guns are a type of air gun designed to fire spherical metal projectiles similar to shot pellets of approximately the same size. Modern BB guns usually have a barrel with a bore caliber of 4.5 mm (0.177 in) and are available in many varieties. These guns usually use steel BB shots, plated either with zinc or copper to resist corrosion, and measure 4.3 to 4.4 mm (0.171 to 0.173 in) in diameter and 0.33 to 0.35 g (5.1 to 5.4 gr) in weight. Some manufacturers still make lead balls around 0.48 to 0.50 g (7.4 to 7.7 gr) in weight and slightly larger in diameter, which are generally intended for use in rifled barrels.
The term "BB gun" is often incorrectly used to describe a pellet gun, which fires non-spherical projectiles. Although in many cases a steel BB can be fired in a pellet gun, pellets usually cannot be fired in a gun specifically designed for BBs. Similarly, the term is also often used incorrectly to address airsoft guns, which shoot plastic balls that are larger but much less dense.

    M19-A "Annihilator"

    I've been looking through an old copy of American Handgunner (Jan/Feb 1980). This looks like it may have been fun: I only vaguely remember advertisements for freon-powered, full-auto, airguns. AFAIK, I never saw one in person. Out of curiosity, anyone play with these back in the day?
