Small, frangible shot cartridges loaded with tiny lead pellets are commonly chambered in handguns like those utilizing the 9x19mm Parabellum cartridge. These specialized rounds are designed for close-range pest control, particularly snakes, hence their colloquial name. A typical load might contain #9 shot, similar to that used in birdshot shells for shotguns. These loads generally produce minimal recoil and are less likely to over-penetrate compared to standard full metal jacket ammunition, making them suitable for use in close proximity to structures or livestock.
The utility of these specialized cartridges lies in their ability to deliver effective pest control at short ranges with reduced risk of collateral damage or injury. Their limited range and lower penetration characteristics compared to conventional ammunition provide a safer alternative for pest management in confined spaces. Historically, such loads have been favored by rural landowners, farmers, and outdoor enthusiasts for dealing with venomous snakes encountered in close quarters. The relatively lower report of these cartridges can also be advantageous in noise-sensitive environments.
