I came across some old Winchester primers. I'm pretty sure of the condition, the boxes are in excellent condition and have been in a very dry area. They were stored in a basement in north eastern Arizona. I'm not sure of the age. They are Winchester boxes of a 100 and the box is mostly yellow with the number #120 and it says they are non-mercuric primers, I looked them up on the net and they are Large Rifle primers. I guess I can test them but was wondering what you thoughts on them are.
Thanks.
