If you really want to get crazy, a mold and some free lead will get you into bullets for about 3 cents each (the cost of gas checks if you need them). These will be different types of loads of course, but fun for plinking.
Case-free range pick up
Primer-3cents
Powder-4 cents (11grs SR4759)
Bullet-8 cents (I included a $50 mold price amortized over 1k rounds and gas checks at $30/1k)
Total-15 cents a round and the more you shoot the cheaper they get.
