Thanks everybody. Matt, I get my horn from anywhere I can find it. I am always on the hunt. Marc, yes, a bit of pinch but I'm used to it. I'm sure I could get 17" out of it, but I would have to adjust the tiller and probably take 10- 20# off the weight. Then I don't think it would have better shooting results. This is the least overdrawn hornbow I have built so far, but 15" really feels like the max. I'm not willing to test this one to the point of failure.
