I've been on a arrow making kick lately. And I'm really leaning towards heavy weight forward tapered shafts. They shoot great out of my bow and the penetration seems the same as my lighter faster arrows. I guess my question is at what point do you start to see diminished returns in heavyweight arrows. (Shooting from a 50-55#,bow). When it comes to deer hunting? And from your experience would using a target be a fairly accurate gauge to compare penetration?
