My neighbor bought an @$$ load of 5.56 from Tulammo in the soviet tins. I was amazed at the quality of the tin because the ammo is crap. That got me to thinking... What else can be sealed in those tins? What is out there that comes pre-sealed like that? The ammo spam cans are a decent size, stackable and durable as all hell. What if we started putting stuff other than Ammo in those?
