UW, I just finished loading 250 rds of 190gr subs last night. I already had/converted the brass. So loaded cost is $.35/rd.

Cost breakdown-

$.05/rd of powder
$.04 per primer
$.26 per bullet

I rounded up the cost of each item as well so this is a high end cost analysis. Yes I have the cost of the equipment but I don't count that because it's already paid for itself 10x over...
