So I dropped draw weight by 2 lbs and nock tuned the arrows. 3 out of the 10 that arrows that are cut to 26” nock tuned acceptably. 3 of the 10 still have 1” paper tears regardless of nock tune. I spine indexed the shafts. Some have as little as 0.002” variance, others have as much as 0.008” variance. Nock fit at the nock end of the shaft is loose on some, tighter on others. When I shortened the shafts to 26”, I cut from the nock end since the outserts were epoxied in the front. This provided a uniform nock fit for “most” of the shafts.
Nexxus has recommended a .300 spine, but at this point I’m not confident that a stiffer spine will give me what I’m looking for, and based off of what I have experienced so far it would seem that I’ll need a few dozen to find a set of shafts that will fly right.
As for “my” nock tuning technique, I go in 1/4 turns, and if that doesn’t work I keep going but in 1/8 turns. So if after 12 we’ll executed shots I have egregious tears, I mark the shafts as “garbage”.
Anything I might be missing?
Semper Fi,
