A little story from when I was young and in Alaska.
A brother-in-law of my best friend was coming home from work and spotted a two year old bull moose standing by a berm pile. He had a 22 with so he popped it in the chest while it faced him. Down it went but pretty quick it was back up. Shot it again and down it went.
He picked my best friend and went to butcher it. Two dead moose laying there. Had to get a couple of us to help get them dressed and out of there. Both were heart shot. Edk
