Although the design of the early air guns was far inferior to today's air guns, the shooting speed of the air gun projectiles could have reached 200-300 meters per second at that time, which was extremely amazing.
The biggest difference between air guns and common firearms is that the kinetic energy source of the projectile is different. Firearms rely on the high-energy expansion gas generated by the intense combustion of propellant and other propellants to push the projectile. The energy comes from the chemical exothermic reaction. The air gun uses the gas pressurized by the air pump to eject the projectile, so the gas pressure generated by the air gun is much lower than that of the firearm, and the power of the air gun is usually weaker than that of the firearm.
