What is .22 eargesplitten loudenboomer?

The .22 Eargesplitten Loudenboomer is a wildcat cartridge, meaning it is not commercially produced by any major ammunition manufacturers. It was created by then 15-year-old P.O. Ackley in the 1960s by necking down a .378 Weatherby Magnum case to .224 caliber.

The name "Eargesplitten Loudenboomer" is a humorous and exaggerated description of the noise and recoil generated by this extremely powerful and loud cartridge. It has a reputation for being one of the loudest and most powerful rifle cartridges ever developed.

Due to its extreme power and noise levels, the .22 Eargesplitten Loudenboomer is not a practical or commonly used cartridge for hunting or shooting sports. It is primarily used by firearms enthusiasts and collectors who are looking for a unique and eccentric cartridge to add to their collection.
