Some time back, there were threads that discussed brass cases that had a light gold color to them. I cannot find the right words to bring them up with a search so I’m asking for help. Does anyone remember the threads and what the conclusions were?
Here’s a photo of the base of a Cal .30 case that is the odd yellow-gold color. The rest of the case, inside and out, is the same color. It appears to be some sort of coating because it can be sanded off and the original brass color is underneath. It’s been suggested that they were cleaned in some sort of acid solution that left them this color. I also have some 7.62mm NATO cases that are the same color. I can’t find them right now but I think they were Israeli?
Anybody?
