Not wanting to be contentious this early in my membership, but here goes. If i remember correctly, hunting with a bow has been banned for centuries.
In the States, where bow hunting is legal, most hunters out for such as deer, use a broadhead, with three razor sharp blades. The idea is that the target will die from massive hemmorage in a very short space of time. I'm sure this is the case on frequent occasions, but all responsible hunters know that sometimes it doesn't and should move heaven and earth to tack down the critter and put it down as quickly as possible. Sounds a bit brutal to none hunters, I know, but it usually isn't. And before anyone asks, I was an archer before I started shooting, and even these days, I do my utmost to be well within range and make sure that the first shot does its job quickly and painlessly. Not trying to take any stance on this, just trying to inform you how things are.
