Thought of this idea the other day.
Bought a bag of new RP 300 RUM cases from a member here a few weeks back. Since they are expensive in the real world and hard to find I figured I'd try to make them stand out. I never can seem to find my brass after it ejects out of my 22' tree stand in the leaves and snow. To my eyes the brass color blends right in with fall leaves. Hopefully they will stick out like a sore thumb now. Used a red permanent maker I picked up in a 3 pack from the $1 store. The permanent marker I used doesn't smell or wipe off. It also doesn't add any thickness to the case diameter so they feed and cycle flawlessly. Im sure tumbling will remove it. Figured it was a good way to mark my new cases vs the old brass that I lost count of the firings. Think I'll be doing this to all my hunting rounds from here on out.
REDRUM!!!!
