365 Mag; I had a similiar problem this year. I shoot an ultratec w/ 28" 3-60. I am maxed at 70#. My broadheads were low and rt. I moved up an arrow and that helped. The last thing that I did was check for fletch contact. I switched to feathers bc/ I couldn't clear my rest and now they are dead on. I don't really care for feathers but my bow is shooting awesome. Maybe you have some contact?
