If you are not apposed to used, back in the 50's thru the 70's or so, Marlin and Mossberg made a series of highly accurate bolt action 22's with target rear peeps and globe fronts. They usually had great triggers, and nice walnut stocks. A lot of guys bought these, cut the barrels down to 16 inches, and thinned out the stocks, making great squirrel guns.
