If you're happy with commercial bulk .223 then by all means run with it, but if you're looking for a heavier low-drag match bullet in front of a powder charge tuned to your rifle, then reloading is indicated.
Likewise with 9mm, there's very little wiggle-room for interesting loadings that aren't similar to commercial vanilla there. It doesn't have the mousefart-to-magnum range of a revolver load.
