So the other day I was looking at my 308 cases wondering how I could mark them with the amount of times they have been shot/reloaded. I have seen competition pistol shooters paint rings around the case but I feel that anything painted or marked in that manner would come off during cleaning. The only solution I came up with that would not affect the integrity of the case was to mark around the Headstamp with a Dremmel tool. Sofar I have been making super light lines from primer edge to edge of head stamp. Not enough to cause issues but enough to see. Any thoughts? Ideas?
