IMHO, the interference fit design concept inherent in the AccuStock bedding block/receiver interface really doesn't seem to me to leave much basis for additional bedding.
But if that's what it takes to float one's boat, have at it...
My only haggle with the design is the ergonomics, but that may be in the process of being resolved too with the AccuFit feature. So far, I've only seen it being implemented with selected long action models. It would seem reasonable to me to expect that to eventually include short actions as well.
Savage generic stocks have usually incorporated some drop at the heel, contributing to muzzle flip, and possibly exaggerating the upward recoil forces against the cheek when recoil is substantial. I have always preferred the stock's upper surface to be parallel to the bore axis, in an effort to relieve such a tendency. That's one of the features I especially prefer in the Stoner AR stock design.
