« on: April 01, 2018, 12:52:22 pm »
Managed to shoot the Osage flight bow (made from one of Clint's staves) off the fingers rather than using the shooting machine.
I got 341 yards ;D using a 28" arrow at about 80#
The best arrow of the four I shot was Cedar with an Elm footing (added to convert a 26" arrow to 28")
310 grain, 7.85mm max diameter, Tip diameter 6.36mm, Nock diameter 7.15mm
40# static spine, fletchings Greylag Goose 30mm x 6mm length x height.

  Del, do you have a spread on th arrow weights you shot and how they did?
The two best shots were only about a yard apart and they weighed 263 and 310 gn.
The two that were consistently shorter 343 and 455 grain. The heaviest was solid Ipe that has now been cut up for footings.
They are all about 40# static spine.
More detail on this post on my blog (written up before todays shot) the arrows 1 & 2 were the best.

This is some great results!  You are in the zone where the arrow is gone out of sight the moment it is released. These kinds of leaps in performance are pretty energizing. This would be a good one to try out at the Bonneville Salt Flats!  You might come close to the existing Unlimited Self Bow Record with good shooting conditions.

Was this with a fast-flight type string?  A good linen string can come pretty close in matching performance.

Congratulations! That sure is very impressive. Nice to see light arrow working better than a heavier one. It means you shoot a fast bow, with good release!

    I believe Allen Case built the arrow for Dan Perry in that shot . I am pretty sure it was well under 200 grains.

Dan Perry’s Record Self bow arrow 154 grains and just under 24” long. It has a mild barrel shape to it with a smoothly rounded over brass point. I used pheasant feathers for the fletches. Construction is split cane (hollow center) joined with hide glue, and maximum diameter around .24”.  The nocks are multipiece Turkish flight arrow style with a thin silk wrap for reinforcement. Dan’s bow had large stiff levers with a linen string.

Do they use an overdraw devise with these short arrows?

No overdraws are allowed for the self bow and primitive simple-composite. Dan Perry’s Record 50# selfbow Record was without overdraw despite the short arrow length. The Primitive complex-composite division allows an overdraw and the Primitive Turkish division allows a sipur-style overdraw.
