My brother approached me with a dilemma this weekend. He borrowed a rifle from his F-I-L to try out and was given some bullets along with it. He doesn't know the exact age of the bullets but suspects that they are from the mid to late 70's as his F-I-L has not shot the rifle in at least three decades. He does know that the bullets have been stored in a cool dry closet the entire time. They apparently look new. I told him that they are probably safe to use since they have been stored in a good environment. But I would run it by the forum members here. So what do you guys think? Okay to shoot or unsafe?
