Dumb hype for a poorly designed projectile. Just looking at that I can see that it would almost certainly fail to achieve the F.B.I. minimum penetration in ballistic gelatin.

But, hey, most people don’t have the faintest concept of physics or anatomy, so they’ve got a big potential market of dim-bulbs to market that to.

I’ll check some of my gun forums and blogs to see if anyone has ripped this one to shreds yet, could be amusing.

.... a poorly designed projectile.

I am also suspicious. Looks like a frangible round, something they used to spatter on specially armored aircraft for gunnery practice. But they were fired from belt-fed weapons, not mags. This baby looks like a poor penetrator and worse, a jam'o'matic in a pistol.

Dumb hype for a poorly designed projectile.

I'm not a fan, either. The primary kill mechanism for a good bullet is blood loss - primarily through the exit wound left by an expanded round. The best round would mushroom to the largest practical diameter, but not shed any parts to carry off energy that should be used by the bullet for better penetration. The only limit is that you don't want to waste a lot of energy on the far scenery so rounds like .357 actually over-penetrate.

The Evans and Sarnow data pretty much showed that any modern round has about a 60-65% probability of one-shot stops with full-metal-jacket rounds, and an 85-90% probability of one-shot-stops with well-designed expanding rounds. That includes 9mm through .45ACP. It also includes .357Magnum, which doesn't do any better because it wastes too much energy on the far scenery - adding to the risk that some innocent bystander will get hurt.

So I'll stick with a well-designed expanding bullet, and I prefer 9mm because there isn't a significant difference in the Evans and Sarnow data between that and the competitors (.40, .45) and I like the extra rounds I can get in the same overall size pistol.

On the other hand, the only way I'd ever have a one-shot stop on someone is if he fell so fast the other 8 or 9 went over his head.

“Just looking at that I can see that it would almost certainly fail to achieve the F.B.I. minimum penetration in ballistic gelatin”

The most violently effective round known to man is the 125gr jhp in .357 Magnum, at 1450fps. It’s beyond rational dispute. It routinely goes about 10 inches deep in Ballistic gelatin and fails the FBI test.

The FBI standard is a very poor standard to use for most people. They aren’t that good at gunfighting, and they pick slugs that are tough and stay together through typical law enforcement barriers. This results in an overly tough through and through round that is little better than ball unless it encounters a barrier. But for the mugger 5 feet away, the rapist at the foot of your bed, or the turd at the ATM, FBI ammo is not the best choice in any caliber.
