The .22 Epperson Cricket (also known as the .22 Pokey or .22 KTW) is a wildcat cartridge developed by "Vibe" based on the .25 ACP where the case is necked down to accept a .224 caliber bullet (as normally found in cartridges like the .223 Remington.

This cartridge is very similar to the .224 Montgomery, though they may not be identical overall. Likewise, both of these cartridges happen to very closely resemble the Russian 5.45x18mm handgun round, all acting as a small handgun round that utilizes a spitzer-type bullet.

Information and discussion by the cartridge's creator can be found at the Saubier forum as well as at the Family, Friends & Firearms forum.
