When I was shooting this weekend to get my broadheads landing at my field points, I was doing a good job at 20 and 30 yards. My group was very tight but it seems that the broadheads seem to land real high up to 40 yards - the field point is the right target. I am using G5 montecs in Easton Excel ST 340 shares. 65 lbs pu;;. I'm not sure why 40 yards will be so high when you are quite close to 20 and 30?
