“Here’s a really dumb question from one who may want to purchase a firearm — does the ammo have a “shelf-life?””
Not a dumb question. If kept in good shape, ammo can last for decades. I have shot surplus WW 2 ammo before.
“if kept in good shape”
I’ve been keeping a lot of ammo in my storage barn. Less concerned about security than temperature extemes. It looks OK, but do you think I should move it inside?
