Okay, me and Jim were discussing Colt 45 ammo and the string turned somehow to age of cartridges and shootability. I said that I was still shooting rounds I reloaded 20 years ago and am still using carefully stored powder and primer that's 5 years old.
He shot a round from 1898 and it worked. I shot WWII 45 ACP in the late '70s/early 80s with no problem.
So what's the oldest round or batch of rounds you've fired give or take a few years?
