I have a cousin that is having trouble getting his broadheads to shoot like his field points. He has paper tuned is bow and still the broadhead shoots 4 or 5 inches to the right. Anyone have any suggestion on how to solve this problem? Here is his set up Mathews switchback xt, muzzy zero, gold tip arrows and muzzy max 3 100 gr. broadheads. Thanks in advance for any and all help!!!
