I practically unloaded mine on my 06 buck. I was unaware that I had to however, first shot, it dropped and was kicking, second shot was in the chest, third shot was in the chest and it never got up once and I wanted to dispatch it quickly. The first shot however was lungs and it hit the opposite shoulder knocking the deer off his feet. We owe it to the game we hunt and to ourselves to unload the quiver if necessary. Even if we have on arrow in the animal, if a second shot presents itself, take it!
