To be fair, I started reloading in 1981, because I could not afford to shoot enough to get better at shooting. And I think I achieved that goal. Prior to reloading, I felt literally like every pull of the trigger was like a buck or more (which is was, even in those days, for my 25-06. I got started with a cheap kit from Cabellas mail order and some powder from a local place that sold it IN A BROWN PAPER BAG! From their larger jug. And #100 .257 pills cost under $20, primers were nearly free.
All the trips to the range to test loads has the welcome side effect that we develop better shooting skills, become aware of other variables that effect accuracy, and generally become better shooters. There are factory load shooters that do this, but SELDOM with the kinds of expensive ammo that long range guns demand these days.....
But the OP has a point, for sure. Now I'm starting to replace older dies with micrometer seaters, bushing neck sizers. Now I retire old brass for a new lot of carefully weight sorted Lapua or other good stuff. Now I obsess about neck tension, and work hardening, where I used to just shoot the case till the neck split and then move on.........
Still wish I had never let that 220 Swift go that put them all in one hole BEFORE I knew that I was doing everything WRONG!!!!!!!!!!
