I ordered 3 Grade 1 Condition M2A1 .50 Cal Surplus Ammo Cans and 3 Grade 1 Condition .30 Cal Surplus Ammo Cans from Clean Ammo Cans. They have New cans, and Grades 1, 2, and 3. Grade 1 is like new with the ammo type stenciled on it, grade 3 is old beaters that need some TLC, like sanding and paint, and Grade 2 is in between. Besides M2A1 .50 Cal cans, they have the newer style M2A2 .50 Cal cans. Where the latch hooks under the bottom of the welded bracket, the A2 can has an extended lip at the top. It keeps the weight of cans stacked on top from pressing the lid down, compressing the seal. See video below. I don't plan on stacking mine more than 2 high, so I'm not worried about it. The 3 .50 cal cans were setting side by side in a cardboard box that fit them perfectly. Inside each one was a .30 cal can with the lid off lying on edge next to it.
Besides several sizes of ammo cans, they have Mil-Spec 4 Pocket Bandolier Ammo Repack Kits with Like New USGI Bandolier and Sleeves to Re-Pack 120rds of .223/5.56 Ammunition. Also stripper clips and guides, and New USA Made "No Glue" Mil-Spec .223 / 5.56 Cardboard Stripper Clip Insert Cartons with Self Closing Lower Flaps! I was emailing back and forth with the guy in the videos about these. He didn't know if they would hold plastic Thermold clips or not. I asked him to send me one with my order so I could find out, then I would let him know. I was surprised to see 25 of these in one of my cans, and they DO work with Thermold clips. I drop 2 clips in at a time facing the same way, then poke my finger between them near the shoulder, and drop the 3rd clip right down the middle. It works extremely well when I do it that way. I'll be ordering another 100 of these soon. It's easy to put up to 29 of these in a .50 cal can, 870 rounds. 28 of them is 840 rounds, just like you'd find in bandoliers. I haven't been able to get 30 of them in a can, so I won't have all 900 rounds of my bulk 52-grain JHP .223 ammo together, unless I drop the last 30 rounds in the can loose.
I cut pieces of cardboard to go in the bottoms of all 6 cans plus my old .50 cal can from Germany. If you trace the can on cardboard and cut it about 3/16" smaller it's a good fit after nipping the corners off. The cans don't NEED to have cardboard in them, but it's flat and level. I put it in the cans so I can dump bulk ammo in and not have it setting directly on the bottom of the can. It won't grind the paint off and have metal on metal contact between dissimilar metals. I have 900 rounds of .223 in a .50 cal can and 3,000 rounds on .22 LR in a .30 cal can. The small can of .22 ammo weighs about as much as the big can of .223. I thought it would, which is the main reason I ordered .30 cal cans. I put my .45 ACP ammo that was in a plastic ammo can into another .30 cal can and filled the plastic can with Trioxane and Hexamine fuel tabs, a few fire starters, and a snuff tin full of Ohio Blue Tip matches, with strike patches glued onto it. Two of my Trioxane bars evaporated, leaving only a bit of dust in the foil packets. I tore open the sides and clamped each one in my vise, one at a time, and burned them up with my propane torch. The stuff didn't even want to burn, it was just the outer coating of the fuel tabs. They're 41 years old this year and it's a wonder they haven't all disintegrated from handling over multiple trips up north and back. If I don't cook with them this year I might start campfires with them to use them up. They were made by some Auto Skate company. I don't know what else they made but was picturing roller skates with little hot-rod engines on them.
