That looks like THV ammo to me.  French company.  They played around with a lot of AP rounds / loadings.  No idea what the current history of the company is, just know that these have been banned from sale / import for a number of years here into the USA.

I just recognized the photo.  AP stuff has always been interesting to me, though I haven't played with it much (no need to IRL).  I just like cartridges, loadings, and anytime something does something WAY out of ordinary, I always take note of it. 

THV seemed to work via having a high speed, very lightweight, brass bullet with a certain pointy shape.  I'm guessing that in 9mm (and this is a wild guess here) the projectile would have been like 75 grains, 1600 fps ?.  Wild guess there. 

The pointy shape I think helped with getting through armor (we're talking about kevlar or related material here), and I'm sure it helped with feeding.  W/o that point, I bet a lot of these rounds wouldn't have fed at all.... esp in the pistol calibers.


KTW did AP a different way, with a very heavy, very hard, tungsten carbide bullet coated in teflon.  The teflon was there not to help the bullet "slide through" the kevlar, but simply to help protect the rifling of the firearm.  That bullet was crazy hard.



Anyways.  Hey everybody, my first post here.  I browse on here some, have several 10mms and love them, but rarely feel like I have anything to contribute..... so since I saw something i could answer, i though why not   Thanks to everyone who DOES post a lot, I like this place
