And speaking of H&R rifles..  Here's a .17HMR..with woodchuck !  That is a large 'chuck, but not my largest.  Perhaps my largest 'chuck ever, was one I got with a Marlin 60.  I didn't happen to weigh it...but he must have weighed at least 20 pounds.. 
    The one I got with the 60 was sitting in the opening of his hole in a mowed area, facing me.  It was about 75 yards from me, so I aimed at his nose, looking to hit his chest...and that is just what happened,,he didn't move, just slumped where he was.
  The one shown was in a pasture eating... a whistle brought him up on his haunches..his mistake, the only one I allowed.
