IT happens, sometimes it has a SH in front of it. Now you have an excuse to go back and start all over and this time use a sharpie to mark the cases.
I also had a big powder mess while pre-loading powder in my brass & setting it a 100 round MTM case. Only did the big mess once as I switched to using plastic caps on my brass right after each case has been powdered.
Tell me the reason for the caps.
