I think I would rather have a "weak design" Enfield bolt action than a shattering Springfield receiver caused by faulty hardening - an example of the eponymous "American Gunsmith" in action?

Good design implies fitness for the intended task, and the Enfield was not intended to be bored out to take magnum cartridges or to be used as a bench-rest rifle, but rather to launch bullets with acceptable accuracy as fast as possible in the direction of the enemy. Something which it did quite satisfactorily.
