once got a screwdriver to go supersonic and embed itself in a concrete wall.
it involved an electro-magnet with a rectangular channel through the middle of it, controlled by a PDP-11 computer. with a little effort, we figured out how to pulse the magnet to launch the screw drive through the channel. however, we ignored the fact that the wall was less than 10ft past the magnet. we probably could have been killed. college. the good old days.

Penetrate, yes. Expand? doubtful. That clay shows the temporary cavity only. That's just my analysis.

Clay is used to measure back face signature on the event the bullet does not perforate the armor. It grossly exaggerates the terminal effect, but it looks stupid cool. |

These types of bullets are certainly interesting. Decent wound cavity, simple construction, respond well to barriers, and punch soft armor. I'll be keeping my eye on them.
Still sticking with gold dots though.

Still sticking with gold dots though. This is something that has caused me significant consternation. These Lehigh bullets do not produce a wound cavity any different than similar FMJ bullets. Unfortunately, some YouTube personalities have started this myth, which Lehigh then ran with. I don't know if it is because they don't understand how to interpret gel results or if it is because they intentionally misled people to help Lehigh sell ammo, but in any case, the belief is absolutely incorrect. Lehigh's "extreme" series is utter bullshit. Same goes for ARX or anything else that claims to convert rotational energy into wounding because magical faerie farts. |

We have shot 38 Super 124Gr IPSC loads through IIA with no problem.
The 7.62x25 zipped right through. 357 Sig will do the same with just about any bullet. With IIA it's strictly about the impact velocity. That's why I use Point Blank Vision IIIA with ThorShield. |

Seems like a simple variation of the concave ogive bullet geometry in order to feed better.

Love it. It's stainless so the tools aren't very hard and they can be awkward to use, but having the right size driver all the time is awesome. Like a pocket pistol, it's not the tool you would choose if you knew you were going to need it, but it's real handy to have just in case.
