Setup sounds fine to me. Your groups aren' t bad. You could tweak it some more if want to tighten it up yet. Are your arrows perfectly straight in the target? You can double check this by doing a paper tune. Setup a paper target to shoot through in front of your present target. It should show perfect holes. Do this with your broadheads also. If you got left,right, hi, or low tears you need some adjusting. Yo u can also check the Forward of Center(FOC) of your arrows for balance. www.bowjackson.com has some info on this, and so does the Easton tuning guide. I also like to check the straightness of all my arrows, especially carbons at both ends. Build yourself a simple double notched jig from wood. Cut out a small V at each end the same. Mark a dot on the wall, and rotate,spin each arrow. Watch it for straightness. Do both point & nock end. The arrows that aren' t perfectly straight ( I always find a couple in a new dozen of carbs) disgard them or use for b.s. shots at home. I save mine for a 3d course extra points, metal target!
