I was raised in Ms and pods were common.Not everyone used them but alot did.Having been around the stuff and seen it work let me explain a little about it.The arrow has to go in the length of the broadhead the open up.A gut shot deer will not go very farand not suffer very long but I have never seen it work on leg shot deer because there is not much blood flow in this area and most of the time the arrow deflect off the bone and not put enought poison in the blood.Most deer shot with poison would would have died anyway it just makes it happen faster.
