Once your done, what is the cost per round
357 Sig 125 grain jacketed hollow points:
powder + primer + bullet = $6.50 per 50
I get once fired brass for about $40 per 1000 but can reuse it quite a few times.
357 magnum 158 grain lead:
Just slightly less about $6.25 per 50 iirc.
I have nearly got my brother talked into reloading. I showed him where he could get components for about $5.50 per 50 for lead 9mm rounds. The key is ordering by components by the thousands. Buying components locally in small volume will cost considerably more.
I don't recall offhand what the others cost but the savings is even better on larger calibers and rifles.
