Since I started handloading, I have added .380, 10mm, .41 Mag. and .45LC to my collection. If I had to buy factory ammo, that never would have happened.
As a matter of fact, before I started handloading, I was in the process of eliminating calibers (starting with .40 and .44), and at one point, my handguns were liited to to 9mm, .357 and .45acp.
I know this isn't the answer you wanted, but here is my advice: buy a single stage press (about $50, used) and a set of dies ($25 new from Lee or about the same used from others). Buy a reloading manual or use the multitude of online resources (most of the major powder manufacturers have loading data available online). Get a reasonably priced scale or a set of Lee powder dippers ($20). Buy a caliper on eBay or from Frankford/Harbor Freight ($25).
Divide the cost of brass by 8-10 reloadings (or more). That will be .015 or so--call it .02 per. Powder is cheap--usually .02 or so per load. The major expenses will be bullets--.08-10 each, primers--.03-04 each. Add it up, and you can load .45LC for 15-18 cents per round.
That's $7.50-9 per box of 50. Lots of folks cast their own bullets and take .08-10 out of that cost--can you imagine shooting .45LC (or any other centerfire cartridge, for that matter) for .05-.08 per round?
