I bought a couple tumblers and a powder measure thru a Craigslist add and it came with a box full of assorted old ammo, cleaning rids and what not. After two days of sorting and cleaning I realized the box was actually pretty rare (maybe). The box has seen a hard life and the printing is barely discernable, but you can make out DUPONT, Smokeless Powder for Small Arms. I've seen plenty of similar Dupont/Remington boxes, but they always say smokeless shot shells, or other smokeless loaded cartridges. If I'm reading/interpreting this correctly this box was for shipping reloading powder.

Right or wrong I have repurposed it for a powder scale box and have it hanging on the wall. I just thought it may be rare and wanted to share these pics.

edit: I wish I knew why all the pics rotated 90 degree counter clockwise.
