Roskoe I think your right on your thoughts. I always can remember the old days with recurved bows and aluminums arrows most bowhunters wouldtell and seeing it happen myself. If a deerwas at 10 yards and one at 20 yards you get more penetration at20 than at 10 yardsbecause are old recurved bows where not center shot, using finger and the aluminum arrow would be trying to straighten out to as much as 10 yards. If your nock is not straight be hind the point your going to lose energy.If the arrow is still in a bend from the shot are bendson impact your going to lose energy on the hit.
V8RangerI think you should look into tuning you bow better.
