Got about 15lbs of powder, lots of primers, bullets and brass from my late uncles stuff. Everything has been stored inside the house. I have only looked at the open cans as most of it has not been opened. The oldest price tags I have found is 1/1976. The 4lb can of SR7625 is about half full and appears to be in good shape. No red dust and no bad odor. One of the lbs of Unique(not shown) just smells old for lack of a better word, no sharp odors or red dust.
