I do, but only because
I bought some RCBS stuff from a fellow that I got a honey of a deal on that came with 9mm dies, 40S&W/10mm dies, RCBS piggyback, ~300 124 grain XTPs and about 3000 once fired cases.
I'm reloading them since I enjoy it, I can't claim to save money considering my hourly wage while working being a basis for my time's worth. But it's a hobby, and I have plenty of materials. I purchased 1k Cu-plated hardcast lead, about 1/2 through those. Once I get the garage cleared, I'll setup the progressive and it will be much more economical in regards to time=money angle.
If you need some brass, PM me, I can part with about 1k without a problem. You can find it for dirt cheap elsewhere too. I'll even give it an hour in the tumbler before I ship it off for you.
For plinking fodder, economics are a wash when considering your time...ususally. For defense loads with JHP, savings are more significant.
