How concerned should I be about 1980s/90s vintage commercial ammo which has been stored in a non-temperaure-regulated area (annual spread 25-105) for approximately 15 years? It has never gotten wet, but it has heated and cooled over the seasons. A bunch of it is .30-40 Krag, which would be expensive to replace, but, on the other hand the Krag would not be my choice of rifle for shooting questionable ammo.
Of course, guys shoot milsurp ammo all of the time which could well have been subjected to FAR worse - so -maybe I am worrying over nothing?
I AM assuming that even if I should chuck the powder, everything else should be OK. I could even snap-off the primers and replace them too, if need be.
Thanks in advance.
