As a means of increasing the power, some airguns are designed so that several strokes of the pumping mechanism forces air into a chamber where it is held under high pressure. Each pump stroke forces more air into the chamber which increases the pressure which in turn increases the velocity of the projectile. The first Crosman airgun produced in 1923 was a multi-pump rifle in 0.22 caliber. Although some air rifles of the past were pumped up by pulling and pushing on a rod that was located below the barrel, the vast majority of multi-pump rifles are pumped up by swing the forearm downward and back up. Because several pump strokes can produce a high pressure in the air reservoir, multi-pump rifles tend to be high powered models. The power achieved by a specific number of pump strokes depends on several factorsbut the most important is the efficiency and capacity of the pump mechanism. Although the Crosman 760 is an airgun of modest power that gives pellets a velocity of over 500-Feet per secondsec, the Benjamin and Sheridan models are quite powerful. The 0.177 caliber Benjamin 397 can fire pellets at up to 800-Feet per secondsec while the 0.22 caliber Model 392 drives pellets over 650-Feet per secondsec as can the 0.20 caliber Sheridan rifles. Of intermediate power is the Crosman 2100 (which fires pellets at over 700-Feet per secondsec)but it is a rifle that is capable of outstanding performance. Many of the classic Crosman rifles including the Model 140, 1400 and 2200 were so powerful that they were popular tools for hunting pests and small game. The modern multi-pump air rifle is capable of excellent accuracy as well as being a powerful airgun.
