Reading it now.
My question, that has rattled around in my head for a while, is related to whether there is a point of diminishing returns for an OBT calculation (barrel length and MV vs nodes) compared to overall length of a (not-skinny contour) medium to heavy but useable barrel.
Part of me wants to say that if the barrel gets below x inches in length, or "short enough" (whatever that means) for say at least 0.700" nominal muzzle diameters, maybe the OBT calcs don't have much bearing and you only need to shoot for the best group... maybe barrel whip/harmonics is all you need.
This could be possible if stiffness becomes the controlling factor in muzzle position at bullet exit, rather than longitudinal pressure wave.
If this makes any sense.
Anyway, not trying to distract from the thread, but maybe these 2 thoughts are related. I don't know. Just thinking.
