The sinew is off a bull moose that I killed at 4yds about 8 yrs ago..I didn't sneak up on him, he snuck up on me..
I was focused on a small spike bull and cow, with no shot they walked into the bush, getting dark, was just about to get up and head back to cabin, when I noticed that a new bull had walked right up behind the cottonwood tree that I was up against. He walked broadside, took the shot, he kept on feeding and died about 10 feet further on.. From the tree to where he was when I shot, was just over 5 arrow lengths..
Then I started shakin...whew...
