As most probably caught, Amouranth had a home invasion in an attempt to rob her crypto. Husband shot one robber and the rest fled.
Colion does a half hour rundown with them both, at their house and using security camera footage as well.
If nothing else this is the kind of stuff that can help mainstream 2A and self defense going forward. Also is an excellent illustration of how shit a defensive situation is, cause almost nothing went "right", but the outcome ended well.
M193 5.56 (55 grain, some of the cheapest ammo you can buy for an AR15) will tumble when hitting a human target or drywall, preventing over penetration, and reducing lethality past a human target or a wall, making it one of the best options for self defense in the home. Within the reliable tumble ranges of M193 (and similar 5.56 ammo), it starts to tumble almost immediately upon hitting a target. Unless, however, we're talking about ridiculously short barrel ARs, which severely limits round velocity, preventing the rounds from tumbling when hitting a target, forcing people to buy more expensive ammo just so it can tumble or expand in target. Numerous tests show cheap M193 ammo is very deadly at its tumble distances when used in barrels at least 14.5 inches in length. The distances vary by study, but when using M193, roughly, a 14.5 inch barrel reliable tumbles out to 50-100 yards, a 16 inch barrel out to 100-150 yards, an 18 inch barrel out to 150-175 yards, and a 20 inch barrel out to 175-225 yards.
For handguns, the only way to limit over penetration through barriers is to use small calibers, like .22, which impedes on one's ability to stop the threat. Self defense handgun ammo, which is supposed to expand and stop in target, when it hits drywall, tends to get gummed up by the drywall, which fills up the hollow point, limiting its ability to expand and slow down, essentially turning it into a FMJ round. Handgun calibers which are good for self defense almost invariably have difficulty over penetrating barriers like drywall.
For shotguns, use smaller shot, like #6 to #8, which don't retain as much energy when passing through barriers.

Huh, interesting, thanks.
I guess the tests I saw were using different 5.56, as I've seen that punch through many layers of drywall without tumbling.
It's probably because a lot of idiots in the gun community fangirl about "new product", which are short barrel ARs, so everyone is getting them without understanding why AR15s are deadly. So, they build short barrel ARs and still use the cheap M193 ammo, not realizing that their short barrels don't impart enough muzzle velocity to get the round to reliably tumble in target, turning their AR15 into a glorified .22.
A good tester should give info on barrel length, ammo type, muzzle velocity (if they have a tester for it), and range to target, which is needed to determine if the rifle and round are capable of making the ammo tumble (if it's designed to do so), at the distance the target is at.
No, 5.56 tumbling is at actual range with lost velocity and stability, not at 25 feet still going supersonic.
5.56 ammo is designed to tumble in target, and that requires higher velocities, not less. Tumbling and fragmentation, which is what makes FMJ AR15 ammo so deadly, occurs more the faster the bullet is travelling, ergo, the closer the target is the more likely the round is to tumble and fragment (if the barrel is long enough to impart enough muzzle velocity to make the round tumble).
For example, the 55gr M193 ammo reliably tumbles above 2700 fps, and has a chance of tumbling (not guaranteed, though) above 2500 fps. The 77gr mk262 round reliably tumbles above 2100 fps. The newer military 62gr M855 rounds are also designed to tumble in target, but again, relies on having enough velocity to do so.
The lmao tumbling ammo meme was always fudd garbage. It was not designed to tumble. It is also not designed to fragment. That is even more ridiculous fuddlore than "it's supposed to wound instead of kill".
It was chosen because with smaller rounds you can carry more ammo for platforms and purposes that use automatic fire for suppression or cqb, while being more controllable. It is a mediocre round that is popular because the army uses it and it's easy to shoot, despite the vast majority of ARs not having auto, and the people buying them not operating in units that would or can make effective use of suppression tactics.
Yeah. Looked up a few ballistics test and, although some tests were pretty half-assed, looks like something like 5.56 frangible/varmint is pretty good if you're worried about overpenetration. Watching that hit gel is pretty amazing; full and basically immediate energy transfer.
Didn't see it versus just drywall (didn't spend too long on this yet), but it might be the best of the bullets that still have adequate stopping power. I'm curious, might look into it more this evening.
I'd say be more aware of safe shooting lanes than relying on modern paper houses stopping anything. If you have a good old brick house, that's better.
