I just started reloading last July. I use a Dillon XL650 progressive press. I load for .380, 9 mm, and .45ACP. I haven't broken it down by caliber, but I can tell you that at this point my cost per round is .22 if I only look at the cost of components.
I use mostly range brass, but there is some store bought stuff in there, as well.
If I include the cost of everything, including the press, dies, reloading books, calipers, scale, bullet puller, etc., etc., then my cost per round is .45 after 8,600 rounds. This cost continues to fall, as I reload more. I feel that I've had a pretty good return on my investment after only 6 months.
Even not considering the costs, the investment has been worth while, simply as a hobby. It keeps me off the couch in front of the TV.
Never argue with drunks or crazy people.
