Speaking of Norinco, does the new 7.62 x 39 come in spam cans for long term storage ? The pictures on your site show a card board box im guessing there isn't any spam cans inside ? If not its just an excuse for more ammo cans :-)
Sealed plastic bags inside, 2 bags of 600 rounds. Airtight is good enough, right?
Though more ammo boxes adds handles for easy carry.
