There is not much to gain by lightening the receiver. When I talked with Chris Bezzina, head of engineering @ Savage, he stated that on the light weight hunter, the lightning cuts on the receiver only took off less than 3 oz. The main reduction was in the lighter barrel contour, a hollow stock and magazine components made from polymer instead of steel. He also stated that the weight of the slimmed down walnut stock was only an once difference than the tupperware.
