Is there a chart in existence that if you have the color of the bullet tip, the cartridge type and country of origin you can determine the type of round. All of this in one place?
You’d have to know under what marking convention it was manufactured as well. The NATO one is easy to sort out. There have been some posts on the forum about this very subject. If it wasn’t so late, I’d look and post links.
Gene Scranton published a loose-leaf series of color guides a number of years ago, that went to 14 sections. It is now out of date and was never quite completed, but it is the best that I know of out there. In addition, it was in black and white and you have to determine color by description and cartridge attributes.
