My main squirrel rifle is a Ruger 10/22 in a French walnut stock with a 20” barrel. It has a Vortex Diamondback HP 4-12x42 in Leupold mounts on it. It will put 10 shots in a nickel at 50 yards where it’s zeroed with CCI mini mags hollow points. It’s probably a 1.25 MOA rifle but I’ve not broke out the calipers or anything.
My preferred “truck gun” is a Marlin 922M 22 mag with a Nikon Prostaff 3-9x40 shooting 40 grain hollow points. It kills at out of its class. It will put 7 shots into the 1.5” at 100 yards.
My favorite, but my baby, is a Win 94/22M checkered stocked 22 mag. It is using a Tasco World Class scope from the late 90’s that has good optics. It shoots 40 grain hollow points around 1.5” at 100 yards.
