Broadhead tuning question
I've shot 4 blade Muzzys for years. They have always shot identical to my field points. This year I tried NAP's Hellrazors. My windage is dead on, but they group consistanly 1-2 inches above my field points from 20 - 25 yards. I have not tried shooting beyond 25 yet. My question is; should I adjust my pins to compensate or move my knock? I'm nervous to move my knock because I've always felt my bow was in tune. I figure Ralph or Vicki would know what to do, they have bailed me out in the past when I have met them at shows.
