I watched a youtube video yesterday on how to pack 7 bandoliers in a 50 caliber ammo can. I was somewhat impressed. 840 rounds on stripper clips and in pouches ready for use.
It is on the heavy side for grab-n-go or bug-out which is why I prefer 30 caliber cans. However as I am a bug-in person so it would be mainly for storage.
This discussion makes me realize I truly need a lot more ammunition. It sure disappears fast when filling ammo cans, magazines, stripper clips and pouches.
