Sorry to be getting back to this so late, here’s what I have:
45lb at 28inches hickory longbow from gibows.com
I was planning on using bamboo shafts (natural taper) that I have hand fletched, and a two blade single grind broad head at 100 grains based on the ashby studies. Arrow total weight is around 500 gn. With out a chronograph I can’t accurately measure velocity for the KE Calculations. What I am looking for is a practical test of penetration to reassure myself that this thing is actually leathal.
