What does "merit" have to do with it? The definition of "obsolete" is 'replaced with something newer'.

If you don't think the .357 Mag has been almost completely replaced for serious self-defense and hunting use you're in dreamland. That has nothing to do with effectiveness - simply that the buyers voted and the .357 Mag lost.


Forgive me my nonsense, as I also forgive the nonsense of those that think they talk sense.
