I was just now reading this thread over for the 2nd or 3rd time (I get bored often), when a thought struck me, and I decided to ask you guys for opinions on it.
I like the metal GI ammo cans, and I have several. Also have a couple of the plastic MTM cans. I prefer the metal for many purposes, BUT what if you have a fire? I've seen ammo in a fire before, and it is no big deal, just pop,pop,pop with no explosion because the pressure never builds up. But if the ammo is in a strong tight steel box, could the pressure build up enough to result in a destructive explosion? Maybe the weaker plastic box could be better in that case.
What do you think?
