If I remember correctly it was about 15 yards, look real close at the eye.........177 predator.
This is one that weighted close to 35lbs (soaking wet, imagine that). Forgot it's posted to my corkboard.
This one took a Beeman round to the head at about 20 yards at night. He stood on a log like a deer in headlights. This was with my Hunter 220. Enjoy.
