The hybrid is capable of higher velocities than a combustion or pneumatic potato cannon because the pressure generated is higher than that in a combustion gun (for most fuels), and the shock wave moves faster than it can in a pneumatic (for most gases), due to the higher temperature. Projectiles fired by a hybrid have broken the sound barrier. [9]
The RML 9-pounder 8 cwt gun and the RML 9-pounder 6 cwt gun were British Rifled, Muzzle Loading (RML) field, horse and naval artillery guns manufactured in England in the 19th century. They fired a projectile weighing approximately 9 pounds (4.1 kg). "8 cwt " and "6 cwt" refers to the weight of the gun to differentiate it from other 9-pounder guns.
Dynamite gun, any of a class of artillery pieces that use compressed air to propel an explosive projectile; FN 303, a semi-automatic less-lethal riot gun; Holman Projector, a naval anti-aircraft weapon; M61 Vulcan, a hydraulically, electrically, or pneumatically driven, six-barrel, air-cooled, electrically fired Gatling-style rotary cannon
The RML 16-pounder 12 cwt gun was a British Rifled, Muzzle Loading (RML) field artillery gun manufactured in England in the 19th century, which fired a projectile weighing approximately 16 pounds (7.3 kg). "12 cwt" refers to the weight of the gun.
A typical factory-made toy die-cast spud gun. The cap attached to the muzzle converts it into a water pistol. A spud gun or potato gun is a small toy gun used to fire a fragment of potato. To operate, one punctures the surface of a potato with the gun's hollow tip and pries out a small pellet which fits in the muzzle.
A cannon is any large tubular firearm designed to fire a heavy projectile over a long distance. They were first used in Europe and China, and were the archetypical form of artillery. Round shot and grapeshot were the early projectiles used in cannon. 18th century cannon projectiles Three different cannon projectiles
A muzzle-loaded cannon: 1) projectile (shot), 2) powder charge, 3) vent. The official weight of the shot was listed at 68 lbs but in reality this varied according to the material of the shot itself; cast iron shot weighed 67 lb (30 kg), wrought iron shot and steel shot weighed 72 lb (33 kg), and chilled steel weighed 68 lb 8 oz (31.1 kg).

By the early 16th century, the Javanese were locally-producing large guns, some of them still survived until the present day and dubbed as "sacred cannons" or "holy cannons". These cannons varied between 180- and 260-pounders, weighing anywhere between 3 and 8 tons, length of them between 3 and 6 m (9.8 and 19.7 ft). [62]
