Can't imagine using a .22 for squirrels. Not sure what you would do with a rifle while also flushing partridge and woodcock in the squirrel woods. Not to mention how dangerous it is to fire a rifle round into the air.

If you really want a challenge stalk squirrels with a shotgun, and get yourself into position so ONLY the squirrel's head is exposed for the shot. Simple way to eliminate damage to the rest of the body.
