Hey Jeff....I know Doug Campbell killed a deer with one, and also another with a stone point within minutes of each other, I think. He also wrote a story in TBM about the hunt.
His point is just a bit different than yours, in that it had a serrated type edge (if I remember correctly), but no matter....that one of yours should work. I made a couple years ago, but they seemed awful "light" to me, and never tried to take something with one.
I did kill a deer with a spoon, though! Good luck with your hunt.
