because you can actually carry a brick of ammo, in your pants and shirts pockets, that is 500 rounds. if you carry it in cci boxes, they are plastic, and the holders make them still, not open the boxes, and not rattle around.
If you bug out in a car, or truck, you can carry 10k worth of rounds easy, that is just 20 bricks, and that is proly about 50 pounds. Plus if you bought your ammo, say 2 years ago or longer, you bought it when bricks were still 10 bucks per brick, 15 max. 10k rounds, would have cost you about 200 to 300 bucks,
super duper cheap, and would last you a lifetime. Or at least until you killed all the Zombies...
Now then, the weapons; most 22lr rifles are about 5 lbs or less, several of them can break down in 2 pieces. So we are talking easy, and light carry. Your super duper hardcore survivalist, will choose a stainless steel, long bbl pistol or revolver of some sort, since really 6 to 10 inches on the bbl, will not slow down the round that much. And so then, a 6 inch pistol, can be easy to pocket or holster carry, again, very light, most pistols, even heavy bbl stainless ones, are 2 lbs. , or less.
If you have ever been in the military, or hunted in some thick woods, you allready know that
F!@$ You vines are everywhere, and even the slightest bbl, over 12 inches long, is gonna get hung up in the F/U vines in front of you, and slow you down , and frustrate you, and totally piss you off, and mentally play a monster mind game with you after only a short while, so being able to pocket or holster carry, while moving through the woods, is a darn fine thing.
