So today I helped my grandparents pack things and move them to their new house, and in the process my grandfather told me I could keep a few things for myself. I've been trying to find some decent quality ammo cans for a while now, and he just happened to have a few sitting there in his basement that he wanted to get rid of. So I kindly offered them a new home, and got them all cleaned up and ready to use for storing my ammo. Now, I was happy enough with just the standard ammo cans, but there was still something else he was wanting to get rid of. So, I went to the other room to go get it, and was met with a pleasant surprise. He had a 20mm ammo can that stored ammo for an M39 cannon used in old fighters. As you can see when it's next to the regular cans, it's quite large. Now I'll have an excuse to buy even more ammo to fill it up. Just figured I would share this with everyone, since I know there's a few people on here who are into the military and firearms. Sorry for the crappy picture quality, had to use my phone and the lighting is not the best in here. I still need to clean the cans more, only gave them a quick wipe-down with a rag to get most of the dirt and dust off. Edit: To give you a better idea of the size of them, the .30cal cans(smaller ones in the pictures) are about 10"x7"x3" dimensions. So that should help to give you a better idea of the size of the 20mm can.
