DC,
I have done quite a bit of paper tuning over the years with glass and some wood bows. Most recommend a distance of 6-8 ft to shoot through the paper. This seems to only work with center shot bows where the arrow doesn’t have to flex around the riser. I shoot mine through paper at 15-25’ which I feel gives more accurate results with non center cut bows where the arrow needs some distance to straighten out.I bare shaft tune as well, but the paper tubing does give a different perspective that I appreciate. You can also try wetting the feathers and shooting the shafts that way to give another perspective of how the shaft itself is flying.
Cheers,
Taylor.
