If the Supreme Court rules that bump stocks aren’t machine guns later this summer, it could quickly open an unfettered marketplace of newer, more powerful rapid-fire devices.
The Trump administration, in a rare break from gun rights groups, quickly banned bump stocks after the 2017 mass shooting at a Las Vegas concert that was the deadliest in U.S. history. In the ensuing years, gun rights groups challenged the underlying rationale that bump stocks are effectively machine guns — culminating in a legal fight now before the Supreme Court.
The “funny” thing is: We don’t. This is all a red herring/sacrificial lamb by the gun nuts to make people think legislature is doing anything.
The two most common rounds used in mass shootings in the US are the 5.56 mm/.223 (AR-15/M-4 round) and the 9mm pistol round. And while the type of round matters a lot, the commonly used variants of each tend to not over-penetrate to a significant level. What that means is that when it hits a kindergartner it stays in the kindergartner and tends to not cause significant damage to the Bluey stuffy they were protecting.
Which, combined with the fact that militaries generally strongly frown upon (if not disable) full automatic fire on rifles, means that fire rate beyond “it is semi-automatic and fires as fast as you squeeze the trigger” is not important. Rapidly squeezing a trigger is considerably more effective than holding a rifle in just the right way to utilize a bump stock or just holding down a trigger to mag dump.
But it provides a “culture war” talking point so that people can feel like concessions are being made when you can still buy almost exactly the same rifle we are giving special forces at a walmart.
Unless we ban all semi-automatic/double-action firing mechanisms (which I would actually be very okay with and consider a genuinely good compromise), rate of fire is largely irrelevant. People aren’t going to be able to flee any faster from someone dumping a magazine with a single trigger pull or a jiggly bullshit.
What matters are getting rid of fucking AR-15s (there is a REALLY good and horrifying article that goes into why the 5.56 round is so fucked up. Well worth googling) and drastically reducing magazine capacities.
A 223 fmj round will go completely thru 1/8" steel at 50 yards what the fuck are u smoking when u say it won’t go thru a body???
9mm may not if its a hollow point because of mushrooming and lower muzzle velocity.
The 5.56 round is a particularly nasty beast and it is well worth actually doing some research before running off your mouth because you think someone is threatening your emotional support assault rifle.
https://www.washingtonpost.com/nation/interactive/2023/ar-15-damage-to-human-body/ is a really good really trigger warning filled article that points out why the AR-15 is so incredibly deadly
In a nutshell, it boils down to the tendency of a 5.56 round to tumble when it hits soft tissue. This is why you see such massive cavitation in ballistics gel and kindergarteners. So it leaves an exit wound but has lost the vast majority of its “stopping power” in the process
Whereas, against a hard target, it is much less likely to tumble.
So yeah. The more you know. But I would settle for “the less you run your mouth about things you don’t understand”.
To expand a little bit for those that don’t want to click through:
5.56 penetrates hard targets because it concentrates energy across a small cross-sectional area due to its small diameter. It delivers a lot of energy to a small point which helps it push through hard objects.
5.56 similarly does not over penetrate in soft targets due to its dimensions: the projectile is narrow and relatively long, with the weight biased to the rear. This means that when it penetrates a soft object, the heavier tail end retains more energy and wants to flip past the tip of the projectile. Because the projectile is long and narrow, it tends to break apart when that happens. That quickly dumps the energy in the projectile and causes the large wounding effect being described above. Since the smaller fragments have less energy, they come to a stop much faster than a solid projectile would.
tl;dr saying 5.56 is capable of both punching through steel and also generally won’t overpenetrate in soft targets is accurate because physics
