Recently my son has shown a real interest in going squirrel hunting. His excitement is contagious and has made me want to get back into it. I haven't squirrel hunted in earnest for years. I have several shotguns I could use, but was thinking of using a .22 instead. Years ago I picked up a bolt action marlin .22 mag. My plinkin .22's I have sited in at 50 yards. Do any of you guys use a .22 mag for squirrels and do you site them in at 50 or 100 yards. I have owned the gun for a while but wasn't sure of its effective range. Sorry if this is a silly question just wanted to get some feedback before I go to sight in. Thanks guys and info is appreciated.
