I just recently bought a package of Muzzy Phantom broadheads online. I didnt realize they were a 4 blade. When i put one on one of my arrows, it is consistently flying 2-3 inches to the right of the spot i am aiming at. I switched out to a few other broadheads i use and they all flew true, under 1" from where i was aiming. I was using the Bloodsport 3 blade fixed blade broadhead as well as an expandable i bought at walmart called spitfire. They both flew right. Any ideas as to why they are flying so off with the Muzzys? Thanks for the help!!!!
