It helps me, when shaping a stock, to think of it, and shape it, like an octagon. Top, bottom, sides, and obliques. Especially through the wrist and forearm area, which are typically more “round”. Form the area to that octagonal shape, then round off corners, rather than just trying to “make it round, or oval”. Also, as Jack Brooks taught me, think of the stock as a fish, which is identical on both sides. Do the same to one side as you did to the other, if that makes sense. Best,
