Spine Suggestion

[tex-archer]

Okay, I have another spine question. I am shooting an Elburg longbow 61#@27 1/2", with a 12 strand fast flight string. The arrows I am shooting are spruce, 65-70 spine, 28 3/4 BOP, with 145 grain points. My draw is 27 1/2". My arrows are kicking when I shoot. All of my shafts are fletched at this time so I don't have one to bare shaft. Do I need to try 125 grain points?

20 gns may not show up with fletched shafts try lighter. I have even shot with no point to confirm my thinking.

A big broadhead will show you what is going on as well as a bare shaft.

My guess would be that your arrows are weak.I think you need about 10lbs more spine.

[The Whittler]

If your LB is not cut to center, then your over spined. Drop down to 55-60 or 60-65.

I think you're underspined, I suggest stripping the feathers off an arrow to find out for sure.

Okay I am gonna strip some feathers off and find out for sure. How much difference would there be if I changed back to a 16 strand fast flight string?

[Don Stokes]

All else equal, it will slow things down a bit and reduce your spine requirements. You can also drop point weight if you're still underspined.
