I normally just fletch an arrow up and paper tune on the patio.
Short distance, and always gives proper reading. Can do at 1 am too (after I get off work).

Have gone back and bare shaft double checked at longer. Same results.

Think the problem comes from folks trying to tune a bow and build an arrow at the same time.

This chit aint that hard.

Running 3 fletch 4" heiical may cost me some speed, but it's boringly good and repeatable.
180-280 FPS

All my arrow build testing is done w FP.
Have NEVER shot a bare shaft w BH on it.

And nope, not even curious.

Think most tuning "how to's" say NOT to try a BH w bare shaft.

Have only had one bow (recurve) that was out of the ordinary on arrow (req'd substantially stiffer than thought).
Out of around 35. Compounds have been pretty easy, except for the Oneidas, that also req'd a stiffer spine.

There I wonder if string over travel the culprit.
New model w string stops might be neat to test.
