Show Use of Dry Ice to Cut Firing Costs New Principle for Shooting Guns Is Invented. DENVER. Have you heard about the new gas-fired pistols, rifles and shotguns? II you're a sportsman, jot down in your notebook to look into this right after the -war. Ray Monner of Denver, a college professor who invented this new firing fir-ing principle, says the ammunition for the new gun will cost about one-tenth as much as the gunpowder gunpow-der type and will weigh only one-third one-third as much. Guns never heat with the gas explosive ex-plosive and barrels never have to be cleaned because there are no powder pow-der fumes or smokes. The recoil is as gentle as a kitten's purring and noise is negligible. "This gun fires carbon dioxide gas, otherwise known as C02 or dry ice,'' says Monner, who is blonde, has a pleasant smile and has spent months in Washington attempting to adapt the new invention to the U. S. army's needs. "I discovered the firing principle when I was fooling around in my home workshop trying to make a toy," he says. "The first gun I made was just a toy that fired common BB shot, similar to compressed com-pressed air rifles. "The C02 is carried in a small cartridge that will hold four ounces and will sell for around 1 cents. This will fire about 2,000 lead pellets pel-lets of .22 caliber that cost about ' 0 I cents a thousand. The pellets a e not mounted in a cartridge, as a gunpowder-propelled slug is, but instead in-stead are placed in a magazine beside be-side the barrel of the weapon. "The explosion of each shot of gas t propels the pellet through the barrel at about the same velocity as if it was fired by gunpowder. The recoil re-coil is gentler than that of gunpowder gunpow-der because the impact is applied to the slug . throughout the entire length of the barrel of the weapon. Gunpowder applies its impact in virtually vir-tually one instantaneous blow. - i |
