Yes- several- beginning with the Model 12.
No it should not. Are you sure the air gun is a .22 caliber not a .25 caliber. Air you loading it right? Are you loading it through the breech? You are using an air gun not a real gun.

Not all pellet guns use C02 some are designed to use a spring or pump. Pellet guns that use C02 are rapid fire guns and do not require re-cocking or pumping between each shot. BUT they usually have less power that spring or pump pellet guns.
