The AR is an over-penetrator while at the same time it cannot be counted on for a one shot stop.
I would like to know the firearm that is counted on for a one shot stop.
The 223/556 is not an over penetrator with the right projo. It is a well-known fact that a 75gr HPBT will not penetrate walls as deeply as 00B.
It’s a well-known fact that an AR is more precise than a shotgun, carries more ammo, follow up shots are faster, a greater variety of spouses can use them.
A simple fun test of ammo types will confirm this. Just line up a bunch of milk jugs. I cannot get three jugs deep with 75gr HPBT, a 9mm pistol penetrates further with 124gr HST hollow points.
The AR15 fires one type of round and it is NOT a one shot stop.
That statement is full of wrong, many ammo choices from a ballistic tip 40gr round that stops 2" into flesh, to steel core that will blow through 1/4 inch mild steel plate, to 77 gr SMK that will reliably make one stop shots to 700 yards. The AR 15 is one of the most versatile, modular long guns ever shouldered by a human......
This subject has been discussed and beat to death all over the web, general conscious these days are an AR15 with the proper ammo choice is superior to a shotgun in HD, look around some sites, Box of Truth has some stuff as well.
Now for the question at hand SHTF
The AR will defend you close up, medium range and at long distance.
It will feed you close up, medium and at distance. I have personal exp with deer that were dead before they hit the ground, one shot stop repeatable…and that was with a Mini-14
It will field a round that will not destroy a rabbit and in the same mag field a round that will crack an engine block.
If placement isn't your thing then you can have 29 more tries, and reload mags in a blink of an eye.
The 223/556 ammo is logistically superior, storing, hauling and acquiring.
One reason the military isn’t running around with AA12’s is logistics, 12 guage ammo is heavy, bulky and not as impervious to rough handling and adverse weather, namely moisture.
If in SHTF, you will be able to find AR-15 parts, mags and make repairs in the field with a tooth pick. The mil spec AR is meant for this. With a Mossberg 500 one bolt may not work in another Mossberg 500 as well as other critical parts. Milspec AR’s will work time after time with a great many companies parts.
The AR is the most common long gun in the hands of American patriots. If you are the guy with a shotgun in the foxhole you are not only worthless in a fire fight but your taking up valuable cover…….you might get called on if a door lock needs to be breached
I would challenge anyone who is sitting on a mountain of shotgun slugs to do more bad than I can, faster than I can with 6 mags of 223 at
50 yards. Chances are I get lead on all targets before you load your second tube.
I won’t even consider 00 buck in such a case because each pellet is 30 cal roughly 50 some gr each going 1600 fps. If you’re lucky 4 out of 9 pellets are on target and once they are there they aren’t placed in a “one stop shot” area unless you’re lucky twice. Not even in the same category as 55 gr going 3200 fps, placed precisely. Even a 55gr fmj is designed to yaw in the flesh, taking a turn breaking bone till it makes its exit.
I could go on and on but I actually hate typing, the facts are out there.....The AR15 fires one type of round and it is NOT a one shot stop is not one of those facts, never was, never will be
