Arrow flight question

[Friend]

It appears that the springy rest is adjustable.
If that is the case, then your issue may be resolved by screwing in the side plate(springy rest).  Moving the side towards Zero or past center greatly increases the spine required. You might adjust the springy rest a couple of revolutions and retest to verify you are making progress. Then continue to adjust to obtain what you want. As you get close, then adjustments will be very small.

I'll try that tomorrow, thanks.  I'll move the rest to the right, looks like I could go about 1/4".  Thanks!

I think your too stiff as well. I'm shooting the same arrow cut the same length out of a 58@28 recurve with 350gr up front. But what puzzles me in your setup is the fletched and bare shafts hitting in the same spot. How big a spot are we talking about?Are the bare shafts on one side and the fletched on the other?hmmmm

[Cottonmouth]

Swampdrummer, when I started this process, they were sliding into the same group, usually withing 2-3" of each other, but with the nocks at much different angels.  It may have been my form (probably was).  Now my fletched aren't kicking right out of the bow so badly, but the bare shafts are hitting left, and slanting nock right.  Off to work, more tinkering this afternoon.

I got to shoot this afternoon, missed last night due to chores.  After I moved my rest so the arrow is centered, my unfletched are landing about 3-4" left of the fletched arrows, even when I upped the field tip to 250gr.  Looks like I'm in the market for new arrows....  

[Friend]

Do you still have any room to move the rest in past center?

[Cottonmouth]

maybe a .25 inch...

[Friend]

Cottonmouth,

You have a great deal of room to increase the dynamic spine requirement for the bow. Continue to adjust the springy rest past center(toward the riser) 1/16" at a time and retest. The beauty of an adjustable side plate rest is that it permits tuning a much larger range of arrow spines.

Good luck you will get there!

Try some 35/55 shafts.  They'll work.  

[metsastaja]

Way over spined and your pushing to extremes to tune the wrong arrow to your equipment.

Switch to GT3555 if GT are your arrow preference

Happy tuning.

Found a test set of Axis ST shafts I got from 3R, cut the 400 to 30.5 and put a 200 gr field tip on it, they group as well as my form will allow, about 2-3".  Whaddya think?

[Cottonmouth]

Those 2-3" groups were 12 yds, no fletching
