Design and Capabilities

The rifle was 4 ft (1.2 m) long and weighed 10 pounds (4.5 kg), which made it the same basic size and weight as other muskets of the time. It fired a .46 caliber ball at a velocity similar to that of a modern .45 ACP

 and it had a tubular, gravity-fed magazine with a capacity of 20 balls. This gravity operated design was such that the rifle had to be pointed upwards in order to drop each ball into the breech block. Unlike its contemporary, muzzle-loading muskets, which required the rifleman

 to stand up to reload with powder and ball, the shooter could reload a ball from the magazine by holding the rifle vertically while laying on his back and operating the ball delivery mechanism. The rifleman then could roll back into position to fire, allowing the rifleman to keep a "low profile". Contemporary regulations of 1788 required that each rifleman, in addition to the rifle itself, be equipped with three compressed air reservoirs (two spare and one attached to the rifle), cleaning stick, hand pump, lead ladle, and 100 lead balls, 20 in the magazine built into the rifle and the remaining 80 in four tin tubes. Equipment not carried attached to the rifle was held in a special leather knapsack. It was also necessary to keep the leather gasket

s of the reservoir moist in order to maintain a good seal and prevent leakage.

The air reservoir was in the club-shaped butt. With a full air reservoir, the Girandoni air rifle had the capacity to shoot 30 shots at useful pressure. These balls were effective to approximately 150 yards on a full load. The power declined as the air reservoir was emptied .

Importance

The Girandoni air rifle was an important first. It was the first repeating rifle
