In my book, the biggest benefit of the upgraded stocks is consistency. Most factory injection molded stocks are so flimsy that rifles have to be held exactly the same way by your shooting rest or sticks or whatever to give truly repeatable results, which is difficult in the field. I have a Model 70 in a B&C stock that I feel will shoot to the same POI whether I'm shooting from sandbags, my bogpod, or rested against a tree, just because of the rigidity and stiffness of that stock.
