Not on an AR auto-loader.
I neck size for a 6.5*47 bolt gun so I have the pilot but think it would be a wasted effort on the Grendel.
Two types of neck sizing; sizing all brass to minimum neck thickness, or to a specific neck thickness (for tight chambers). The Grendel neck is too big and the system too robust for even minimum thickness sizing to show a measurable difference. Just buy quality brass, like Lapua.
