Ive often wondered why the belt hasnt been carried on right up to shoulder..giving a fatter external with same internals...much stronger case but longer case life and ability to handle higher pressures

Because the belt already supports the weakest part of the case surrounding the primer pocket. The rest of the case body is supported by the chamber wall, providing your sizing die is set properly and the necks annealed it will be the web expanding that kills the case.
