Had someone give me a couple thousand Federal primers and its a primer I'm not familar with. I was using CCI years ago and switched to Winchester a few years back and have used them ever since. There are about 1000 Federal 215s that are in Red and Black or Dark Blue boxes and 1000 Small Rifle match that are in white and black boxes. Does the color of the boxes indicate one type being older than the other. The guy couldn't remember how long he had them but had kept them in his gun vault with a dehumidifier. Does the color of these boxes give any indication as to how old they might be and does anyone have any idea on the life of primers kept in these conditions. Thanks in advance.
