I just changed my rest from a Tm hunter to a Ripcord drop-away. My arrows shot in the same place with either broadheads or field tips, now my field tips shoot low and left (same distance 20-30yds) with my fixed broadheads as zero. Doesn't matter what make of broadhead (tried 2 different makes), shoot 1 broadhead it hits center, 1 field tip=low left. I checked my set up twice everything is fine. My question is, if this is common? What do I do to practice with durring the off seson? Should something be set differently? I like all the functions of the Ripcord, Don't want to change back.
