I have a older neighbor who asked me what I thought he could get for his metal oil drum that’s filled with 12,500 rounds of Federal XM855 5.56 ammo, yeah, no oil I said that he should take it to a gun show with a small weigh scale and bunch of ziplock baggies but he wrinkled up his nose at me. So how much should I suggest to him for the whole drum at a fair price?
