As proof of there durability, this is a 160-grain field point on a hickory arrow.
What you can barely see, due to my poor picture-taking skills, is that the tip is severely flattened. That's all the damage that came from two dozen shots into 3 pieces of 1/2" plywood. All shots were at 10 yards, from broadside to "never-shooting-at-a-deer-from-this-angle" quartering away. Afterwards, it was shot into a cinder block for good measure. That blew off the nock, but that was it. Between all that, plus beating the shaft back out the plywood with a hammer, I'm pretty happy with it.
So, I guess that's it. Over the next few days, I'll post some more on this thread. Final tuning, pics of the finished dozen, mounting broadheads, and I suppose some more torture testing for the fun of it.
Like I said, these hickories aren't the second coming. Cedar and fir have better tolerances for straightness, and once they begin to bend, they can be a pain to straighten back into line. But with a little elbow grease, they make a shaft of great heft and durability that flies with the best of them. At the very least, they make one heck of a stumper/ small game arrow.
