My wife has been shooting her Diamond Edge and her field tips fly great. Today she decided to try some hunting heads and they aren't flying even close to where they are supposed to. She was shooting at 20 yards, and the NAP Scorpions are about 3-4 inches low and left, and the fixed blades are about 6-8 inches low and left. She is drawing about 40 pounds, using Beman ICS jr arrows, and all the heads are 100 grains. She is using a Hostage rest and a wrist strap release. I know that not all the details are necessarily pertinent, but I was wondering if someone could point me in the right direction?
