...and the one truth that it eventually all comes back to: You won't save any money, you'll just shoot a lot more.
I load .40 for ~ .20 per round
The way I look at it, that's not free, Range brass is time and casting is a hobby unto itself, I've looked several times into casting and for volume it just doesn't make sense, 5k rounds a year is a lot of time melting lead even in a 4 cavity mold, And lead isn't free all the time, if it is you have to scrounge through a lot of stuff to get your lead.
I'm just saying there are some hidden costs
My son and I have several thousand dollars invested in equipment and supplies - all (other than our reloads) could be sold today for far more than the price we paid, try that with your fishing equipment, boat, motorcycle, golf clubs etc. The peace of mind from knowing we will never be "caught short" when we want to shoot or if SHTF, is worth a great deal to me. We will continue to purchase ammo, supplies and equipment when we find great deals but don't ever have to pay an excessive price to maintain our hobby. We currently have over 30K of loaded ammo, and enough components to reload at least that many more (as long as we reuse a portion of the brass).
I don't think as much about going to the range anymore and shooting a 100 rounds of .38 spcl. That was the intent with reloading. To be able to shoot more...and get ready to reload .30-06 for my M1. Maybe I'll take that up later this year.
45ACP's $.09 for me as i cast too....
