Looking for some of the big ammo cans, bigger than the standard which holds about 8 bricks of 22's which is what I consider the most common. I don't know the official caliber designations but ones I have seen will hold about 3-4 cases of 9mm depending on how packaged. I also would be interested in the tall ones which I think might be called 120mm mortar (???). Looking for ones in pretty good shape and fair prices, prefer to find ones that are not just being stored outside in the weather.
