Yes, you can cast bullets for almost nothing, normally, until you start talking 10,000 rds or so per year. Then you have to go buy the lead at scrap yards, and you have 3c apiece or so in 9mm, maybe 5c in 230 gr .45's. I'd never bother to buy commercial cast, swaged or jacketed bullets for practice. I shoot too much for that. 10,000 bullets, which is just 1/2 year's practice for me, quickly pay for a Star Progressive sizer-luber, a pair of 6 cavity lee Molds, and a used, propane fired plumber's furnace. such a setup will let you turn out over 800 finished bullets an hour. Get the big progressive Lee press for $200 or so on Ebay, and get the bullet feeder accesory for it, and it will load 800 rds an hour. So you can have 400 bullets an hour, at a savings of 15-20c per shot, for commercial reloads, depending upon caliber.
