Lungs...bigger target. My moose presented a hard quarter shot resulting in my only hitting one lung. My saving grace was that the arrowhead was buried so deep in the upper right leg joint he couldn't really move. He stood there a while, laid down, stood back up and tried to move, laid back down, then got up again and stood there a while. I was seriously fighting the urge to crawl close for a second shot but thought I had double lunged him so I stayed put. He laid back down and stayed down in canola that was tall enough to conceal his exactly location. Didn't actually see him until I was 5' away...that was interesting. Glad he was dead.
