lone hunter, cool story. On my first bear hunt in Saskatchewan I wa sitting in a treestand with a guide and shot a black bear. Like you my arrow didn't pass thru but instead came back out the entrance side, with no point. The guide says "you didn't get very much penetration" to which I replied, "I SAW it go in up to the feathers I don't know why it came back out" . Anyhow 20 yards later, bear down, death moan. The next day I went back to look around and found my snuffer buried 3/4 of the way into the tree that was directly behind where the bear was standing when I shot him. It was so deep I couldn't even get it out, just left it there.
