Primer life

Thought you guys might be interested, I shot some .308 handloads yesterday that were made with RWS primers from 1973. Got some decent, under 1/2 MOA groups from 300 yards (WW cases, 748 powder, Nosler 168 J4's). No misfires, they still work!

I'm not surprised at all.

The worst case I've seen is W231 powder that was 10 years and stored in a garage that was hot or cold depending on the weather. It shot as good as new powder. I've never used primers over 7 years old and anything of mine is stored indoors where the temperature is consistently too cold(my wife) or too hot(me).
