Not much ammo in the can, just a few stray rounds and you can see what it did to the brass, copper jackets and exposed lead. I have Lee handloading kits for the 9mm and 44mag so I will test some of the primers. The ammo can was in a tote with other stuff that didn't get corroded including a can of Dupont SR7625 and a can of Hercules 2400 which are fine.
