Solid Copper with a little design change (versus Lehigh) and coated.

Well therein lies the fault, the twist is different for different guns, some have left hand rotation and some have right hand rotation. ${$default_huh_smiley}$ The nose cuts could be straight so it would be the same for either twist rotation. $:-\$

It is a mixture of copper powder and plastic.

Most handgun rifling is right-hand twist.

There is a gel test video on youtube. They don't work so great. Another gimmick cartridge. That is why I carry at least one magazine of FMJ.

Intercooler, I've replied to a post of your about these once or twice before so I'm glad you were able to pick some up. How's the durability on the bullets? Do they hold up as well as a true solid-copper round? I was curious to see how tough the "composite"-type bullet it uses would hold up, especially considering that it's blended polymer and such. I see they definitely move right along so they must seal well enough and hold up in the chamber/barrel; Were you able to recover any after firing or send some for the pull-downs yet?

I will send them for gel and pull-downs. My time messing around with them, they seem just as solid or more than Copper. If The Shadow wants to take a hammer to one of the pulled bullets... fine by me!

${$default_laugh_smiley}$ that would be an interesting test method. I know there's been some questions/concerns from guys here about the hardness of lead and the suitability of different levels of hardness for different purposes. I suspect that these bullets are softer than a traditional all-copper bullet and that allows them to seal the barrel quite well which could account for some of your 100+fps gain your gun yielded... Either way: this design seems like an interesting innovation. Thanks for the information.

There is a write-up in American Rifleman about this ammo this month. Typical fluff piece you tend to see there (eg those guys wouldn't say crap if they had a mouthfull).

Yeah, I read that. Snake (oil) round, at best. Less lethal (??) defense ammo is a farce, but they have a following. Maybe effective on the beach in summer, but in practical tests I've seen, they fail against heavy fabric and light barriers. The concept has been around for 30-ish years, and still doesn't make sense.

I kept having the same thoughts as I read the article. The boat propeller analogy sounds great, but the reality of side by side gel tests is they perform like FMJ.

I am not signing up to be shot by one, but if I had to be shot, I would take these over a good JHP any day.
