Sorting brass to sell. Doing it by pound. Yes, I could count 100 pieces and x by 10 but I have a non-digital postal scale and I want to touch it as little as possible; I have a nasty dog bite on hand and a toddler running around here somewhere; so... I came here. I've been doing 12.75# for regular 45ACP to be safe. You think another 1/2#, would 13# even suffice or is there even that much difference? I googled a bit but got many different answers. Thanks!
