.22 Eargesplitten Loudenboomer
.22 Eargesplitten Loudenboomer is a wildcat rifle cartridge.
This humorously named cartridge was developed in the 1960s by P.O. Ackley for Bob Hutton of Guns & Ammo magazine, and was intended solely to exceed muzzle velocity. Ackley's loads only managed, firing a bullet. Based on a.378 Weatherby Magnum case, the case is impractically over-capacity for the bore diameter, and so the cartridge remains a curiosity. The advent of new slower-burning smokeless powders may have changed the equation.
