| This very interesting stuff. To some extent, I can say I have noticed similar results/effects with my own arrows. However, I am a bit unsure as to why.
I am not saying it isn't to do with the spine of the arrow being different at different positions round the circumference. Could there not also be the nock alignment issue at work here too?
I have rotated the nocks of arrows by 180deg, and brought them into the group. However,in that case, the arrow shaft has stayed in the same orientation with the bow/button. I assumed from that, the change was brought about by the nock and shaft being better aligned one way than the other.
By keeping the nock the same way round on the string, and rotating the shaft, is it possible to eliminate the change in nock/shaft alignment?
Some nocks, fit more tightly in one position than another, could a loose fit, or tight fit, cause the arrow to land out of the group? |
