The plastic “rib” that is in your stock – was designed to be there for a reason. Rather it is positioned to dampen barrel harmonics – and aid in accuracy for this particular stock/barrel combination.
Lock it into a lead sled at a range.
Speaking of harmonics, perhaps you could explain to us how locking the rifle into a mechanical fixture that doesn't move freely with recoil…will replicate a hunter shooting the said rifle at game…or even come close to duplicating normal sight in/load developement conditions.
