All the Benjamin .22 cal were made of Brass and painted Black. What condition and what model are you asking about.
Solid Brass was created in 1993.
Solid Brass.
It all depends on the bore size, and if you really mean GUN as in "gun or rifle." The larges Pellet bore is 50 caliber and that would be a Air Venturi .50 Cal, 275 Grains, Solid Core, Soft Lead, Round Nose pellet. If it's just a pistol it would be a .22 caliber pellet and that would most likely be a Predator Big Boy Senior .22 cal, 28.5 Grains, Domed. Remember air gun/rifle pellets come in all sizes. .177, .20, .22, .25, .9mm, 357mm, .45cal and 50 Cal.
