Pull my finger
I hate to even post this but it is so stupid of me that I'll take my licks. I was re-sizing some LC 223 brass tonight. First three seemed awful hard to get the expander ball in.. But by damn I did it. Got suspicious and checked it out. I had 204 brass.. A few days ago I was reloading some more 223 and needed a plastic bullet box to put em in. So I dumped out a box of spent 204 into a plastic bowl.. For some reason tonight I thought I had put a buncha LC brass in there.. Turns out I was wrong.. Looks like you can make 223 brass outa 204 with enough trimming.
