I now date all of my power cans when I purchase them. However, I have part of a keg of 700 X I purchased in the mid seventies. I have recently shot several 12 ga. rounds that were loaded from the keg in the 80's with no issues. I have newer powers to use however, I must consider whether to reload with the older power or not. Any thoughts?
I just finished of an 8-pound keg of Red-dot last year, I bought it in the early 70’s. I quit reloading shot shells a few years back and it sat in the cabinet for years. When the powder shortage broke out, I used the Red-dot in cast rifle loads, it shot just fine.
We have a canister of hot cocoa mix from 1963 at the cabin. It was there when we bought it and I never threw it away. Now I keep it as a conversation piece.
I also have a jar of Coffee Mate from the 1970s. It's a glass jar with a metal lid. On the back, there is a wok offer. If you send in a few sheckles with the order form on the back, you can have your very own wok set. I should send it in and see what they say.
