Guy I know used to say he would rather have a sister that worked in a whore house than a brother that shot Squirrels with a shotgun.
I'm in that camp too....
Yup, there is only one proper way to wack squirrels, head shots and 40gr solids(my 10/22 likes the old Winchester Wildcat stuff). I know guys that favor a 20ga for squirrels, not a fan of picking out shot of my squirrel stew.
