Ok... I'm a little bit of a prepper... not the over the top & off the deep end type of prepper, more of an emergency prepper... if one were trapped in a blizzard, swamped in a flash flood, or other condition that may cause you to need to spend the night ( or longer ) in the truck, or the woods, or ??? I keep a "stuff" bag in the truck, & this shotgun will be an addition to the "get home" bag... if everything were wet, I'm thinking about the ability to start a fire, it could be to keep warm, or cook the instant soups, or heat food, or boil water, cook some small game you may have shot or ???
main purpose would be to hold shot shells, but everything should be good for more than just one use, if it's going to be stashed in the truck for extended periods...
my original thought was the magnesium fire starters... if the shell holders we made of magnesium, you could start many fires on wet wood, with the high heat given off from burning magnesium shavings...
the shot shell box does not fit into the 2 pockets on the bag that holds the folding shotgun
