Does anyone know where I can find the spine deflection chart for carbon express arrows. Or does anyone know the deflection for the heritage series 250 or 350. I want to load some up with about 400grns up fromt for some extreme FOCs.
I looked around online and cant seem to find a chart that shows the deflection in inches.
I remember reading you subtract the number on the shaft from 650 to give the spine, so 650-250=400.
Carbon Express lists their deflection rates on their website
www.carbonexpressarrows.com (http://www.carbonexpressarrows.com)
CX Heritage 250's have a spine deflection of .387 and the 350's spine is .320.
