Rat-shot is very small lead shot (usually #12 shot) which is typically loaded into a cartridge not generally considered a shotgun shell. The most common cartridges loaded with rat-shot are the .22 Long Rifle or pistol or revolver cartridges. Using rat-shot cartridges allows one to convert a handgun or rifle into a small shotgun suitable for short-range use. Rat-shot (also called snake shot) is generally used for shooting at snakes, rodents, and other small animals at very close range. It is used by farmers in rifles for the control of birds flying inside of barns and sheds, as well as for killing rats, for the simple reason that rat-shot will not damage the metal roof of a barn or the metal sides of a shed, while still being effective against small pests at close distances. The maximum effective killing range of such cartridges is very limited, typically being less than 10 to 16½ feet (3 to 5 meters).
