Nice looking arrows.What are the shafts made of ?
The most important part of any point, is that it be very sharp.That's why I like obsidian and dacite. (Most knappable stone can be gotten sharp enough) It should be sharp enough to shave hair.It's not enough to punch holes in a deers lungs,you need to really cut them. (The front part of the lungs preferably) Quartering forward in from behind the near shoulder is a very lethal shot. (especially if the near,front leg is forward) Sharp point and shot placement is everything.
If you do things right and be patient,the shot will be given to you. (Probably not on every hunt, but; it will happen)
