Oldsap, you have a beautiful way of expressing the obvious!
It takes what, maybe 45 seconds to swap out screwed-in dies? So even if "quick change" die bushings were free and instantaneous they wouldn't be worth much for saving less than two minutes of time per reloading session.
I like Lee's priming Classic Cast system. My liking it don't make it good, so that don't amount to much, just a personal taste sorta thing I suppose. People do have different tastes, otherwise no one would buy anything made by Gov'mint Motors. ??
