Is Subsonic Ammunition Effective For Ground Squirrel Hunting?

Ammunition Characteristics

Subsonic ammunition is designed to travel at speeds below the speed of sound (approximately 1,100 ft/s), which reduces the sonic boom and noise associated with supersonic rounds. This characteristic makes subsonic ammo suitable for hunting in areas where noise needs to be minimized, such as in residential areas or during dawn/dusk hours. For ground squirrel hunting in California, a good starting point for subsonic ammo would be a 40-grain or 60-grain bullet, with a muzzle velocity around 1,050-1,150 ft/s.

Hunting Techniques

When hunting ground squirrels with subsonic ammunition, it’s essential to use a high-powered scope (7-10x) and a rifle with a good muzzle brake to compensate for the recoil. The flat trajectory of subsonic ammo allows for effective shots at close ranges (20-50 yards), but it’s still crucial to aim for head shots to ensure quick and humane kills. In dense cover or thick vegetation, a scoped rifle with a good magnification can help identify and engage ground squirrels quickly.

Additional Considerations

When selecting a rifle for ground squirrel hunting with subsonic ammunition, consider a caliber with a flat trajectory, such as a .22-250 Remington or .17 HMR. These calibers are well-suited for hunting small game and can handle the heavy recoil associated with subsonic ammo. Additionally, consider using a bipod or a rifle rest to stabilize the rifle and improve accuracy, especially in dense or uneven terrain.
