Ihave a mathews z7 set at 70lbs. 28 1/2 inch draw,cx 250 arrows. The bow groups badly and at 40-60 yards the arrows drift right,are my arrows under spined or is it a rest issue.have not had this problem in the past with my mathews Lx but was shooting cx 300 arrows,the pro shop says the 250 arrows should be fine.Any help on the topic would be greatly helpful, thanks
