There are no shortage of posts on CGN claiming very significant savings by reloading common calibres, 9mm, 45 ACP, .223 Rem, etc.. Occasionally these cite some pretty uncommon sources for component materials and/or some fairly extensive (for most) efforts. More commonly, prices for purchased ammo gets overstated by quoting NEW ammo priced in 50 rd boxes instead of more appropriately quoting commercially reloaded 1000 rd lots. This is accurately, what you get when you reload. Also commonly, setup costs for the reloader get way understated by omitting tools and other paraphernalia required. It doesn't end with the "starter kit" purchase.
For the majority of new and experienced reloaders, who simply buy equipment and components from retail sources, then put the stuff together, for the common calibres, $$ saving is insignificant !! In the majority of cases you can't justify the capital outlay with the meagre cost saving of rolling your own.
NOT to say you shouldn't reload!! If, however, frugality is your one and only motive, you are in for a disappointment with these calibres IMHO.
