The .22 CB Cap (Conical Bullet Cap), also known as the 6mm Flobert, is a more powerful version of the .22 BB Cap rimfire metallic cartridge, which was invented by Louis-Nicolas Flobert in 1845. The .22 BB Cap and .22 CB Cap are interchangeable and are relatively quiet, low velocity cartridges, designed for indoor target shooting.
