It's first letters. Rifle Red, Pistol Purple, Shotgun Silver. And a sign on the wall with one of each color dot used and the type beside it. A red dot says Rifle and so on. Written inside the cover of the loading logbook along with color dots. Anywhere else you want to put a key.Yeah. Then, I gotta remember what each of the colors are. It might work/be helpful if all the rifle cases were red, pistol cases were purple, etc.
