You asked about the costs of setting up to reload. As an absolute minimum: You will need a press (see my post above...Lee Challenger, $18.50), Die set (Lee 3-die set incl shell holder, $18...Midway), Shell holder (free with Lee, about $5 for other die suppliers), beam scale (about $30), set of calibration weights (free from a friend with a calibrated scale...trimmed pieces of copper or aluminum wire), powder trickler (free...use a rifle case twirled in your fingers), loading data (free from the powder manufacturers). Say $60 to $75 total.
Very nice to have: A drum powder measure (Say $40...set by your beam scale, so its not an "either or"), vernier caliper ($10 from Graf, another of their 50% off sale items...otherwise about $18), plastic shell boxes (about $10 for ten from Midway), box labels ($5 from Midway or Graf...you could write on 2-inch wide adhesive paper tape for almost free), vibratory tumbler ($28.49...another Graf 50% off item...otherwise about $45 from Midway), tumbler media (10-lb corn cob, another Graf sale item at $5.99). Graf pays shipping...Midway doesn't.
As with the actual reloading, your set up cost will depend upon what deals you can find by shopping around. Second-hand equipment in good shape is fine...check for reloaders getting out of the practice...gunshows and gun shops. Tools, scales, and powder measures don't wear out unless grossly mistreated...mine have been in heavy use for 50-years and are as good as new.
