What is a .340 in the wood arra scale?
Interesting question. I just put a carbon 340 on my wood spine meter. Got: .225 deflection for about 115# spine rating.
Pretty stiff.

sorry, misunderstood the question.
From the wood charts, .340 deflection should be between 76 and 77# spine.
Self bow is right if you are talking the wood spine chart. I thought he was asking about the difference between the carbon chart ATSM and the wood chart AMO.
Clarify your question. But guess you have both answers now.

For me I find you can't compare a carbon spine to a wood spine,carbons recover and react much different then other arrow materials.
A wood shaft that deflects .340 with 2 lb on 26" centers is a 76.5 lb spine.
Thanks guys.
My gold tips a barely stiff enough at my draw. Was considering wood, just looking for a good place to start.
