This is my manual for arrows that fly strange.

Take heed of the note

The detailed descriptions below are for a right-handed shooter. Up and down adjustments with the nock point is the same if you are right handed or left handed. Left or right adjustments however are reversed. For explanation purposes, all discussion will be for right handed shooters. If you are left handed just reverse all left/right indications.

Ray — thanks for this link. On first glance-through it looks very interesting. I have printed the entire thing out for study and future reference. Who is the author? dave p

The website looks like it is owned by O.L. Adcock

Adcock?! Well shucks, what “sounded” like good info just “became” good info. Both O.L. and his lovely wife are world champ flight-arrow shooters … which requires a level of fine-tuning so precise it might as well be rocket science. Now to find an uninterrupted hour to read it as it deserves to be read. Thank you, ttf

Nock left for a lefty should mean stiff. Glue on a heavier point and see if it straightens up.

The website is Adcock’s. That is about the best info for bareshafting from what I understand. However, with wood arrows I don’t recommend bareshafting. IMO, paper tuning works much better with wood arrows.
