Beman classic spine

[beachbowhunter]

Does anyone know the spine deflection of the Beman MFX arrows? The website doesnt have them posted. Is a 400 = 0.400 deflection? I'm used to CX arrows and the label and spine have no relation to each other.

Thanks,

Yup, the spine and the sizes are the same number. 340=.340, 400=.400 and 500=.500

Thanks, I wish they all were so simple!

Here is a quote from their site.  It appears the "400" model # does directly reference the spine:

"Shaft Spine
All Beman shafts use a spine deflection number to determine size. Spine is measured by hanging a 1.94 - pound weight in the center of a 29" shaft to determine deflection (spine). This is why an ICS 500 (.500") is a lighter spine than an ICS 340 (.340")."
