The Caselman Air Machine Gun
A correspondent sent me the links to the following videos. An air powered machine gun that fires 32 caliber bullets at a decent rate and velocity. Sounds intriguing, to say the least. And the videos look interesting too. The “Home Gun Smith” has the plans for sale on their site.
Here’s more info from the e-mail I received:
The CASELMAN works under 3.000 psi air; muzzle velocity is 790-800 fps (in .308/7.65mm, .355/9mm, and .451 calibers); rate of fire 600 rpm; with a single air charge it´ll shot 100-105 times within this range of power; in .451 caliber, using 225 grains bullets (NOT round balls) it´s muzzle energy is 311 foot pounds. We can be sure it is as accurate as the best closed-bolt submachineguns of the same caliber, using similar (pistol) bullets, something like 100-120 meters. It is a closed-bolt weapon, and since airguns are ever more accurate than any firearm, it is not hard to imagine that. Of course if we pick the best bullet (weight, profile, hardness) to our rifling path and barrell lenght, and we build with the utmost care the gun, magazines, and load with care each magazine, we´ll get even better accuracy with the Caselman AMG.
