I truly don't know what the real answer is. So far in my life, which equals 54 years of shooting a lot of different brand bows, and different models within a brand, I have had two bows that shot identical with broadheads, and practice points. What is weird is that these two bows I am referring to were "real short" axle to axle length bows >>> one was a Clearwater Ultramag 33", and the other is my present bow a 34" PSE Enforcer. I always tune my bows the same whether for 3D, or hunting, and that is with a slightly high left tear through paper. I am right handed.
