My longest shot was a joint venture with my nephew that took countless hours and countless dollars over a few year period.
It was 2144 yards on a unsuspecting Rockchuck.
Very nice, confirm a wild rangefinder? Have not seen one of those in quite a while.
My best is 575yards on a wounded blacktail that someone else had hit quite a bit earlier. Saw a bachelor herd of bucks on a far ridge and saw the buck limping real bad, left hip was broken. Rem M7 in .308 over a backpack and he went down cleanly.
