I'd still bed the forward receiver and under the shank... a recent "experiment" (long story) with an 84L MT in 30-06 definitively proved (at least in that rifle) that groups will shrink substantially. And yes, that rifle was "dead nuts" in the barrel channel too.

Your 280AI sounds awesome... what a great round!
