The bullet that struck U.S. Representative Steve Scalise last week was travelling at somewhere between 1,100 and 2,600 feet per second. The projectile, a 7.62 x 39 bullet, hit the House majority whip with between 370 and 1,550 foot-pounds of force. The rifle round, which is longer than a pistol projectile, likely also began tumbling after its point collided with his hip. That meant that the tip didn’t just bore straight through him, but rather that the whole length of the projectile rotated over and over through Scalise’s body, ripping a wider hole and distributing a bigger shock wave throughout his bones and tissue.
The 7.62 round is not as fast as the .223, the round fired by the AR-15 (America’s most popular assault rifle)

The Weldon caliber was somewhere between a .22 and .50 cal. /s
Here is a new one.

Copper cnc milled bullet therefore one of the most accurate
Also, designed to tumble upon impact; does not expand, but tumbles.
All their bullets are designed to tumble upon impact.

9mm

38
45
10mm
223
5.56
338

Damn auto fill!
IMI makes a couple of versions of 115gr +P+ rounds.
Federal has a couple rounds that clock at 1400ft + also.
With modern ballistics, the 9mm can be a beast. It’s why the .40S&W is getting tossed by PD’s in favor of it.
Someone please do the math. 2400 fps with 1 in 10 twist is how many rpm?
The info in the article is sort of redundant to shooters.
Bathtubs, the real killers, don’t get the press’s attention because they don’t make loud noises.
“The rifle round, which is longer than a pistol projectile, likely also began tumbling after its point collided with his hip.”
The 7.62X39 was not designed to `tumble’. A shot-out barrel on some heirloom Afghani piece will `key hole’ a target.

The Russian 5.45 was designed to tumble, like the American 5.56.
“There is an air cavity in the nose that makes the 5.45mm tumble and yaw upon impact, which moderately increases lethality.”
A .357 isn’t all that much bigger than a 9mm; 0.3543307 vs. 0.357 (9.07mm). A .357 has a whole lot more energy behind it however.
“Bathtubs, the real killers, don’t get the press’s attention because they don’t make loud noises.”
I think governments kill more people than bathtubs.
1400fps...with 95gr bullet and 6 inch barrel?
“Someone please do the math. 2400 fps with 1 in 10 twist is how many rpm?”
BTW, Rev/sec, would be a better number. 2400 ft/sec/12= 200 in/sec., 1 rev/10 in 200 in/sec/10 in/rev= 20 rev./sec
Here’s a bullet stability calculator. Have fun!

Would they have preferred them to be shot with a .22-250 (4000 fps) or maybe a .250-3000 bolt action?>>>. I love my 22-250 browning. it is a tack driver.
I have an original M16A1.Load it with original M193 spec ammo and it is unbelievably destructive.Bullets tumble and break up,wounds on varmint size critters are massive.
tried it two different methods. 2,880 rev/sec
2,400 ft/sec * 12 in/ft = 28,800 in/sec
28,800 in/sec * 0.1 rev/in = 2,880 rev/sec

Mostly big-bore black powder or heavy .308 shooter myself, but I’ve seen thin-jacketed prairie dog handloads fail in rotation while going down range.
your tagline - I guess I might be vette14
Not from any of the ballistics tables I've seen. The 7.62x39mm's 123gr projectile out of an 18" SKS barrel MIGHT achieve 2,300 fps.
The bullet's behavior in the target is radically different than the faster 55gr 5.56mm with its crimping groove which makes for dramatic terminals ballistics for target engaged an less than 75yards, as at the Frank Mann Field from the dugout to 2nd base. And we do not know if the projectiles were FMJs or had a small meplat at the nose -- not a "hollow point" -- although the uninformed might mistakenly call it that.
The article was filled with typical non-shooter inaccurate references. "Assault rifles" have a selector switch and can fire 3-round burst or full-auto. "Assault weapons" (a term created in law) is a semi-auto rifle with certain offensive cosmetic features. The SKS is not even an "Assault Weapon" by the now defunct Crime Bills definition.
You are, of course correct. I divided where I should have multiplied.
What .22 cal has 2600+ fps muzzle velocity??? The "high velocity" .22s the kids and I shoot are like 1400fps.
“The SKS is not even an “Assault Weapon” by the now defunct Crime Bills definition. “
But they are outlawed by name as “assault rifles” by name here in CA.
Almost all hunters, especially in the west, use a much more powerful round to hunt deer and anything larger.
The 5.56 round fired by the M-16 or the AR-15 modern sporting rifle is not even legal to hunt deer sized game with in most states.
Neither of these rounds should be considered high powered rounds. They are in the low end of mid power rounds at best.
This author has a great fantasy about tumbling bullets when they enter the target. Bullets that don't hit bone travel is a straight line and exit the body taking all the excess energy out the exit hole. Much energy is displaced but much is also wasted.
When a bullet hits a bone it is usually deflected and will probably break or shatter the bone, but none of them are made to tumble upon entry. That is just the authors BS anti gun TV Hollywood fantasy crap.
This author has hyped everything to try and sound like he understands firearms and ballistics, he doesn't know crap about firearms, ballistics and has shown himself to be an idiot.
I'm a gunsmith, a hand loader, and I build truly high powered long range comp rifles. I shoot both long range rifle comp and combat pistol comp. I've been doing the gun thing for over 40 years.
I'm also a retired AB Ranger with six combat tours. I could also tell this moron the difference between what a 5.56 round does to a person compared to the 300 win mags sniper hits from our cover shooters.
But I won't because there is nothing to know except that is way more nasty and much more destructive. Anything else is not coming from me.
This stone headed idiot touched on bullet terminal ballistics but he has not the beginning of the first clue as to how it works or what he differing end results are.
In the end game the total of the powder load, shape of the case, barrel length, rate of bullet twist, the flight path/trajectory of the bullet, bullet weight, bullet design, and velocity mean everything. What you are after is one single comparison number in all of this when you do the final math. The telling number is the Ballistic Coefficient of that round fired from that particular weapon.
The terminal ballistic lethality, different than downrange and terminal ballistics, of the bullet varies by velocity, bullet weight and bullet design. A hollow point expands and deforms at one rate, a soft point at a different rate, and a bonded ballistic tip expands and deforms at yet a different rate. If a bullet is lead core it acts one way and a solid metal bullet, like a barns bullet, acts differently. All of these differences mean that the different bullets depart/shed, energy at a different rate depending on the rate of deforming and the frontal mass of the deformed or mushroomed bullet as it passes through a body.
We missed the part about loads, long grain powder or short grained powder and all of the other steps we go through to find that superb accuracy and instant lethal result.
OK way too much knowledge for most but with this I want to make a point.
This author doesn't know crap about ballistics or how bullets act, react, impact, or depart energy.
He read the kindergarten prep book on ballistics and tried to sound smart. He is a "ballistic stupid" idiot trying to impress people with the very little knowledge he has. He is an idiot writing for an audience of gun ignorant idiots.
Most of these wanna be shooters love the FMJ bullets.. They are always the cheapest on the shelf. That is probably what he was shooting.
The FMJ rarely comes apart but it will deform and deflect when it hits a bone. If they don’t hit bone the shape does not deform, they do not tumble, and they make nice neat little holes clear through the body.
All states that I know of do not allow big game hunting with FMJ non expanding bullets. These bullets do not depart enough terminal energy into the animal and cause too many wounded and lost animals.
