Hey guys!! Long time no talk!
For those who may not know me, I'm Billy Berger, and I was involved with production of the video. I've been watching this thread for a while, reading what everyone has written. And I wanted to clear up a few things about this new fire hardened bow technique.
First off, I don't know as much as Keith Shannon does about this technique, since he's the one who came up with it and has been experimenting with fire hardening bows for over 2 years. I was brought in as a cameraman and editor. That's my expertise. I was shown the technique and filmed it. I have a pretty good idea of how it's done, although everyone will have their own way of fire hardening and there is no ONE way to do it. However, Keith's experiments have shown, at least for him, that using traditional dry heat from charcoal or a fire gives better results as opposed to using a grill or some other modern contraption.
I have seen, and filmed, fire hardened white wood bows outshoot Osage bows that pulled 5 lbs more, and I've seen fire hardened bows match, and even surpass the speed of fiberglass traditional bows of the same draw weight. Some folks questioned the accuracy of the draw length we shot these bows at during the chronograph tests. The bows were secured, with clamps, to a shooting table and Keith had precise draw lengths noted on the table to be sure he drew the bows precisely to the draw length indicated on the video. Although you can't see it on the video, there were marks indicated on the shooting table. Of course he drew the bows by hand because that's what we had; the only way to have been pinpoint accurate would have been to use a precision shooting machine with a predetermined draw length and mechanical release. But the number of test shots we did (and many didn't make it on the video due to time constraints), showed that the speeds we got were quite consistent. Precision shooting machines would likely give similar results in speed tests, though there might be a difference of 2 or 3 FPS in either direction.
Keith really torture tested these bows and put them through their paces because he wanted to be certain that his results were consistent, accurate, and repeatable. He wanted to be sure this wasn't just a fluke. And every time he's made these bows he's been greeted with the same results. He's got a lot of credibility in the hunting industry and there's no way he'd ruin that by making false claims about the performance of fire hardened white wood bows without proving it to himself. He repeated to me personally, many times, that he wanted to be sure that what he was claiming was true, and that the speed results he was getting were accurate. I saw them for myself and I've shot his fire hardened bows...and they're fast. I'm so confident in their abilities that I'm currently working on a fire hardened hickory bow that I plan on taking to South Africa next year on my first ever African Plains game bowhunt.
