The .30-06 ammo I shoot at CMP matches is 1943 Remington production. I've shot a few rounds that dated all the way back to WW1. Also squeezed off a couple WW1 .45ACP rounds once just to make sure they still worked. I'd trust my life with them! A Stevens rifle in .32 Rimfire once passed through my hands. I had a partial box of ammo that was circa 1900. It shot just fine. Also put a couple rounds of .41 Swiss Rimfire (VERY OLD) through a Vetterli once. Those rounds pre-date your ammo by 100 years!!!
