Opening day @ 7:00 pm. Shot @ 8 yards through lungs ran 30 yards and fell. Magnus Stinger 100gr. BH. Maxima Hunter weight forward carbon arrow. The arrow broke in half, half way through, broadhead passed through and the fletching end fell out. Hit rib entering and exit, think that is why it snapped. Maybe arrow had not stabilized, or I could have hit a blade of swamp grass I don't know. At first I thought I didn't get a good hit, with the arrow sticking 16" out. But found that half a few feet away from where he was shot, and a ton of blood a couple feet past that, and there he was. It was a great relief finding him so close. Can't belive my moose season is over already, I'll have to spend the fall looking for bear.
