In one side and out the other is about as deep as you can go. I like the skinny arrows for hunting but not 3-d,and I like to shoot the same arrow for every thing since I only have one bow. I seen a video of a turkey being killed with the guillotine, and it looks very lethal with a neck hit. But they may be hard to manage in your quiver, and I don't need any extra distractions while bow hunting.
