Unless your arrows are bent, it's not the arrows. I know that for sure. It doesn't matter what heads you shoot, they should be shooting better than what you are getting. I personally use a NAP Nightmare broadhead. For me, they flew the same as a field point from my crossbow (TenPoint Phantom) out to 40 yards. I never shot past 40. I have shot plenty of Hortons and I know they are capable of shooter much better than the results you are achieving. I wonder if you just took off your sight and just kind of bore sighted it so to speak or made a make shift pin sight, if that would work good enough to see if it was the sight. BTW, do you have the scope or the red dot?
