Snake shot (also commonly known as rat shot and dust shot) refers to handgun and rifle cartridges loaded with small lead shot. Snake shot is generally used for shooting snakes, rodents, birds, and other pests at very close range. The most common snake shot cartridge is .22 Long Rifle loaded with No. 12 shot. From a standard rifle these can produce effective patterns only to a distance of about 3 metres (10 ft), but in a smoothbore shotgun (or garden gun) that can extend as far as 15 metres (50 ft).
