Squirrel rifles are my main addiction, sometimes kinda depends on the hunting for me which one gets packed around. Early season i mostly carry around whichever .22 strikes my fancy at the moment, usually loaded with some sort of Subsonic HP's...some of the more used:
some of the most carried in early season; a CZ452style with 3x9EFR, and a Cz452American with 3x9 Compact which has a Leupold Dot Reticle:
Late season, when leaves drop & long shots become more common, its one of the 17Mach2's...
Kimber 17M2 Hunter with Burris 3x9AO Compact:
Classic Varmint 17M2...weaver V16 has been pulled, and it now wears a Sightron SII 4-12xAO.
One of the places we hunt has had a lot of feral hog activity over the last few years, when we start the deer feeders they tend to hang around & i switch to .22mag, just in case we run into pigs; we usually shoot several hogs a year while squirrel hunting so during that time i try to hunt with a .22WMR and usually shoot Rem 40gr PSP's or CCI gamepoints, which are not too rough on squirrels.
T-bolt .22mag, 4x12 Elite on top:
