One of my buddy's has been stock piling 22lr ammo, since the mid 80's. He currently has 1 ,5 gallon drum full of loose ammo ( well about a half inch from the top). So I have a couple of questions how many rounds do you think would be in there? What is the lifespan of loose rounds? What would be a fair paying price? This is a very mixed lot, I believe he purchased what ever he could find and tossed it in. Thanks for your input!
