I only load .38 Spl and.380 ACP (and not a lot of .380) I did the math and spreadsheet thing once also- loading 9mm, .223, etc. at home provided a lot less motivation in terms of pure $. And that was with the "Monkey" doing the work not being paid anything. My .380 efforts are usually hampered by the lower recovery rate of the brass- gotta love revolvers for that aspect as I just eject the spent brass straight into the bag, as well as a slower rate of rounds loaded due to my dexterity with the smaller cartridge and bullets.
All my SD stuff is commercial loads.
