"Upon release with both hands, do nothing." If you don't, you will never know for sure what your arrows are doing. Most import of all, this ain't rocket science or brain surgery. i just got in from shooting 200 arrows, 16 in the quiver. I held every one back for a bit and worked on good tension, with the slight straight back motion in my release hand,(normal thing with good back tension), and keep the bow steady. Sure, I shot tight groups, split a bunch of nocks and feathers. It happens when there are too many arrows in the target. I noticed that perfectly similar arrows, 1918s that are shot with as near as I can power, still do not all fly exactly the same on every shot. Gusty swirling wind, slight variances in the release fingers, my pet wren singing next to me in my apple tree, whatever, it is always good to allow for some slack in the system. I did prove that it is possible to stick 16 arrows into a pile the size of a large apple without breaking any from 18 yards. I also proved that one could stick 16 arrows into a pile the size of a watermelon and damage four and those four were not in the middle. When I get my new bow, it will be shooting woods and I will only be shooting three arrows at a time and I will not be aiming at my own arrows just to see how tight my groups are.
