John my friend,
I plan to load the 150 Nosler Long Range Accubond with latest Doppler measured data. I consulted the Berger twist calculator and it suggested a twist faster than 1-10 in order to maximize BC. Who am I to disagree with Berger?

With the excellent concentricity of modern bullets, there isn't any reason to under-twist a new build.
On the Other hand, I just don't see bullet manufacturers having much success producing & selling bullets that require a tighter twist than something that has become such a widespread standard as the 10" .270
As MD says below, there's calculators, and then there's calculations, but the proof is in the results. In any event it won't hurt to over-stabilize a wee bit.
Upon reflection, your shorter barrel will reduce MV a bit, perhaps enough that some extra twist is of benefit ?
I think you're swimming against the tide of tradition. Innovation never comes easily, but is its' own reward.
I am most interested in hearing of your results.
Cheers
