Lost Brass?

[Bunk]

Brand  .45ACP brass with your mark.
Paint the case head with DYKEM blue or red layout fluid.
It is very durable unless you clean with steel pins.
Cases that have been shot three or four times and tumbled clean still show the mark.
Drill a row of proper size, proper depth holes so only the case head shows. Then drop in cases, and with a fast swipe of a brush, dobber, or spritz with an aerosol can and, Fanny is your Granny, you are done.
