Even considering that the equipment is fully amortized, there is still the value of your time.

I shoot jacketed bullets on almost all of my reloads and they are a little more expensive than cast lead bullets, so my cost per 50 round box of 38 Special comes out closer to $12.

If I add in the value of my time that box comes in closer to $90. So, unless you want to "sell" your reloading time for about the same hourly wage as a child chained to a sewing machine in a Bangladesh shirt factory, don't do it to "save" money.
