Behold the Girandoni air rifle, a 20 round high capacity tubular magazine and air reservoir which fired at roughly the same velocity as a modern .45 ACP. It can punch straight through a 2x4 at 100 yards.
Invented by Tyrollean Bartholomaus Girandoni around 1779, this revolutionary rifle is four feet long and weighs a manly 10 pounds. It's semi-automatic rate of fire and, for the period, its immense firepower reserve made it a fearsome thing to contemplate in battle. No appreciable bang, no smoke and at least 20 rounds before its punch began to diminish.
