The Southeastern Naytives use to "fire harden" their cane arrows, and from the accounts I have read, those arrows killed just fine, even to the point of peircing through heavy leather and chainmail on the Spanish explorers. Of course, there is no mention of the bow poundage, I'll bet it was heavy though, that's back when "men, where men" !! I have never tried it though.
Depending on what the shaft is your using, you could, if you wanted, glue on modern field points. There is not a set "target point" for primitive arrows, that I'm aware of any way, meaning, as they did 200 years ago.
There was different points used, but they all had one thing in commen, they were ment to kill.
Maybe if you post this on the "Pow Wow" section, it would get more thought, and a few more answers. Not that the folks who watch this section would'nt have a good answer, it's just that the pow wow section would be seen by a lot more folks.
