@gorillapaws . If it were up to me, NOBODY would carry. You are failing to understand the situation. Even gorillas protect their territory, to the death. It’s a part of nature. Not one I’m fond of. But apparently, in this world, it is what it is. Yes. Shotguns are perfectly capable of outperforming even an advanced marksman, with an AR (within 25 yards, or so.). But you can’t carry a shotgun, in your pocket. There are numerous flaws, to your logic. Perhaps, just ignorance of firearms in general.
That’s ok.
A 12 gauge shotgun, loaded with 00 buckshot, is basically multiple rounds of a 0.22 caliber firing weapon. That’s not going to stop someone who is wearing body armor, with trauma plates. You have a LOT to learn, about firearms, before making your assertions.
I understand, and agree, with your concerns. But you apparently have very little knowledge of the subject.
A .270, is a small caliber bullet as well. But with much more velocity. A 0.243, is more than sufficient to kill a large deer. But it’s not the size of the projectile. It’s the velocity.
An AK-47, generally uses a 7.62×39 bullet. That’s a 0.30 caliber projectile. Consider that a .380 subcompact, is the preferred weapon of concealed gun carriers. Still a .30 cal projectile, but with far less muzzle velocity. That doesn’t mean that you can shoot it out with a pistol, versus an AK, or SKS (Chinese version of the same weapon.)
Barrel length, grain count, and many other factors, are variables. Even the tip of the projectile, is very important, if the weapons have similar caliber. It’s not as simple as, well, we both have a gun.
If you are interested, there is a great deal of literature explaining the differences.
A deer hunter, for example, will choose a very different bullet (of the same caliber,from the same gun) as a boar hunter.
Even a FMJ round, is highly different from a defense round, when considering what soft tissue it is to be used against. Police usually use hollow points. They are lethal, against soft tissue, but will not ricochet, like an AP round. Therefore, hypothetically, reducing the amount of unintended targets.
An AP round, has greater penetration, but less stopping power, than a hollow point.
If you want to stop a car engine, use an AP round. If you want to stop the driver, use a hollow point.
A single action gun, is more accurate, but has a much slower rate of fire.
A double action, or semi-auto, is far less accurate, but can put more rounds in a target.
Full auto, is extremely inaccurate. Most users of these weapons, are trained to aim at the knees of a target, with the likely rise in the muzzle, as it fires.
A bolt fed weapon, is the most accurate. But is much slower, to reload, and typically has lower magazine capacity.
A revolver, is less likely to jam, but has less capacity.
A semi-auto pistol, will be less accurate, and more likely to jam.
There are many different types of weapons. All, have different designs. And many different types of rounds, that have pros and cons.
Even the same weapon, can have different parts, for different reasons. Some ARs, are gas operated. Some, are piston driven. Some are better at being used in mud, or dessert. Others, are better in perfect conditions.
Shotguns made for large game, are generally heavier than those used for fowl.
The length of a shotgun barrel, can make it more lethal up close, or at a distance. So. Your home defense shotguns, will have the shortest barrel possible, to spread the shot widest, at close range. Conversely, duck guns, will have the longest barrel possible, to spread the shot as far as possible.
A gun, is not just a gun. Nor is it’s ammo…
I have several different types of ammo, for each of my guns. And usually different mags, with each type preloaded. But. You have to be aware that spring loaded mags, will get worse if fully loaded, all of the time. So I rotate clips, and rounds. Rarely, do I keep them fully loaded, for more than a few weeks.
