.22 Eargesplitten Loudenboomer
The .22 Eargesplitten Loudenboomer was a Wildcat Cartridge developed by P.O. Ackley in the 1960's for Bob Hutton, a member of Guns and Ammo magazine's technical department. The intent of the cartridge was primarily breaking past the 5,000 feet per second barrier that tends to exist as a limit to modern smokeless powder. It appears to sometimes be described as being a necked down .50 BMG, but this is actually not true. The cartridge is actually based on the .378 Weatherby Magnum, necked down to accept .224 caliber bullets. However, according to Cartridges of the World. machinist Zachary Weighman did make a novelty inert cartridge called the ".22 Earsplitting Loudenboomer", along with a .17 version called the .17 Incinerator, both based on the .50 BMG.
