SHORT_ANSWER The minimum legal caliber for ground squirrel hunting in California is .22 caliber rimfire, which includes .22 Long Rifle, .22 Magnum, and .22 Short. This caliber is allowed for hunting ground squirrels in the state. It's essential to check local regulations for specific requirements.

Hunting Methods and Regulations

Ground squirrel hunting in California typically occurs from March 1 to December 31, with some areas closed during the breeding season. The daily bag limit is 20 ground squirrels per hunter, and there’s no possession limit. When hunting ground squirrels, it’s crucial to use non-toxic ammunition to prevent lead poisoning. Make sure to check the California Department of Fish and Wildlife (CDFW) website for up-to-date hunting regulations and any specific restrictions in the area you plan to hunt.

Choosing the Right Rifle and Ammunition

For ground squirrel hunting, a .22 caliber rimfire rifle with a scope is an excellent choice. The .22 Long Rifle cartridge is a popular and effective option, offering a flat trajectory and relatively low recoil. When selecting ammunition, look for high-velocity loads that can deliver accurate shots out to 100 yards. A good scope with a magnification range of 4-8x is recommended for pinpointing ground squirrels at varying distances.
