If you buy 150gr federal soft points when they're on sale for 10 bucks a box, and your only reason to reload is to save money, it's probably not your cup o' tea. I can tell you I save 25+ a box vs comparable factory loads in my centerfires. If you went ultra caveman basic, you could pay for your loading equipment with a bottle of powder, a box of bullets, and a pack of primers.

Or, and this is the more likely option, you could wind up like the rest of us reloaders. First, you try to save money starting up. You're nervous to try out your first load, but it works out great. Heck, that's the best your rifle's ever shot. You'll try a different brew next time, after some more reading. Before you know it, you can't help yourself every time you see a deal on components. "5 bucks off on powder? Wellllll I suppose I'll grab a few of those. 8 bucks off a 100 pack of bullets? Heck, I better just clean the shelf of these babies. I'll need them eventually anyways. Primers..only a few bucks a hundred, I spose I'll pick up a few of those, just so they're handy. Ooooohh, that tool would make things easier! Maybe next time, after I replace those dangerously bald tires. But I do have this sale voucher. It wouldn't hurt to have I suppose."

This is a math problem. There won't always be people willing to take the risk of loading for somebody else. I know I won't load for anyone other than myself and close friends. So figure out equipment cost of equipment you want, and your ammo cost vs factory cost to make your decision.
