Head shot on a squirrel from far enough away that I aimed dead on with the wide part of the duplex on a Burris 4x12 scope on 12x. The rifle was zeroed at 50 yards. 83 yard offhand shot at a squirrel with my Marlin 60 with Federal Lightning ammo. Squirrel folded at the shot, but I couldn't find the hole until I looked at his ears and noted it went in one ear and out the other.
