I have just spent a couple of hours shooting Bare shafts at a boss.
Santa bought me a new set of ace's this year, lucky me! I had heard about knock tuning but had never done it before, I will never again buy a set of shafts and not do this again.
I set my bow up and warmed up in the normal manner, I then shot a couple of dozen arrows fletched ACE's to see my grouping at this range (15m 6 arrows 50mm dia group consistant)
I then bought out my new packet of ACE's and split them into two sets of six. leaving 6 in the tube I shot six arrows at the boss what I found was that I had a small group of three arrows and three arrows were loose from the group by about 2 -3" I then shot the three arrows which were loose again to the same result leaving the grouped arrows in the boss I then rotated the nocks on the loose arrows 90deg this was done while the arrows were in the boss and shot them again I found that one of the arrows came into the group and two stayed out leaving the grouped arrows I then then rotated the nocks again untill all the arrows were in the group. I then pulled all the arrows and started the process again this time the group size was about the same as my fletched group earlier but I found that, I still had a couple of arrows which were a little loose from the group I repeated the above process again, but only turned the nock a little way this improved matters and my unfletched group was smaller I then put these arrows to one side and did the same with the second six arrows ensuring that the flew to the same area as the original group again I found that there was 3 arrows loose from the original group my second set of six were tune into a group about the size of a 2 pence piece This set I have maked up as 1 - 6 and the second six as 7 to 12 with 2 arrows which were hardest to tune into the group as 11 and 12.
What I have found interesting is my unfleched arrows now fly tighter groups consistantly than my fletched both sets are identical in weight and spine but my original set were not tuned this way. This exercise only took about 1 1/2 hours and I think it was time well spent.
I have a set of socx arrow wraps also from santa but I am not sure now if i will fit them or not incase they make a difference, your views are appreciated
