Casting is pretty simple, until it isn't...
I'm all for cranking out piles of bullets from a 4-6 cavity mold, tumble lubing and loading. Often that provides great results, sometimes the results are less than desired and then the fiddling begins.
That said, I seem to learn something new with every mold, and every gun I load cast for. And a global keep it simple just doesn't always work because there are issues of throat and/or forcing cone dimensions, barrel twist rate, pressure, bullet bearing length, etc.,
Some people are itinerant tinkerers, and the journey for them is more important than the destination. Nothing wrong with that, it's a hobby, whatever turns your crank.
