RE: Sighting In/Grouping
With a fixed head htting to the right usually suggests an underspined arrow. It just won't show up as readily with field points or a mechanical head like the Rage. You don't say, but you need to list things like the weight of the bow and drawlength, length of the arrows and type of fletching, etc.
Another way of testing this is to just turn the weight of the bow down about one turn and see if the fixed heads group closer to your field points. Many guys do it, but don't get caught up in the idea that you MUST shoot the bow at a certain weight. Deer can't tell a five pound weight difference. Those limb bolts are one of the most overlooked tuning tool on a bow.
Anyway, try out changing the weight and come back and give us that other info. Then come back and let us know what happens.
