Quick Answer
For squirrel hunting, a factory load with a 20-40 grain bullet and a muzzle velocity between 1,800-2,200 FPS is ideal, typically found in 22 Long Rifle or 17 HMR cartridges.
Choosing the Right Cartridge
When selecting a cartridge for squirrel hunting, consider the power and range required for the task. For small game like squirrels, a lower-powered cartridge is sufficient to ensure quick and humane kills. The 22 Long Rifle (22 LR) and 17 Hornady Magnum Rimfire (17 HMR) are popular choices, offering a balance between cost and ballistics. The 22 LR typically produces a 20-40 grain bullet with a muzzle velocity of 1,800-2,000 FPS, while the 17 HMR produces a 15.5-20 grain bullet with a muzzle velocity of 2,100-2,200 FPS.
Optics and Range Considerations
When choosing a factory load, consider the optics and range at which you’ll be shooting. For close-quarters hunting, a high-velocity cartridge with a short-range flat trajectory is ideal. For example, the CCI Velocitor 22 LR load, with a 32 grain bullet and a muzzle velocity of 1,995 FPS, is a good choice for hunting at ranges up to 50 yards. For longer ranges, consider a cartridge with a flatter trajectory, such as the Hornady V-Max 17 HMR load, which produces a 17 grain bullet with a muzzle velocity of 2,190 FPS.
