What form of sodium chloride in a non leathal shotgun shell could inflict very painful, but rarely deadly, wounds?
Shotgun shell A shotgun shell is a self-contained cartridge typically loaded with multiple metallic "shot", which are small, generally spherical projectiles. Traditionally lead was used, but increasingly steel, tungsten or bismuth shot has replaced lead, due to laws designed to protect the environment. A single, large projectile known as a shotgun slug can also be used, and numerous specialty rounds such as less-lethal rounds (e.g. beanbag rounds), flechette rounds, lead-dust rounds for door-breaching are also available. An old non-lethal shotgun load consisted of a shotgun shell loaded with rock salt, which could inflict very painful, but rarely deadly, wounds, and was therefore popular for scaring away trespassers.
Cetylpyridinium chloride Cetylpyridinium chloride (CPC) is a cationic quaternary ammonium compound used in some types of mouthwashes, toothpastes, lozenges, throat sprays, breath sprays, and nasal sprays. It is an antiseptic that kills bacteria and other microorganisms. It has been shown to be effective in preventing dental plaque and reducing gingivitis. It has also been used as an ingredient in certain pesticides. Cetylpyridinium chloride may cause brown stains between the teeth and on the surface of teeth. However, these stains can be easily removed by a dental hygienist during a routine check-up.
