.223 THV which in French means "Tres Haute Vittesse" or very high velocity in English, Brass spire tipped projectile, from South Africa headstamp 13/87.  A short lived armor piercing round that was ruined by the anti pistol caliber AP laws back in 1986.  With its negative parabolic ogive, the projectile has long range, high velocity, high penetration, and also causes serious wound channels.  wolfgang

Very cool!!  I haven't seen that round before.

Cool. How the heck did they get the powder to stay in the case?
The sparks from cutting it should have sent that round through several buildings, killing at least 3 puppies.

THV bullets give me the weirdest boner.
ETA- only have seen examples of pistol bullets.  A THV in 5.56 would be OBSCENE.

the very few guys that have a CCW license here in Italy have carried those THV rounds in handguns for a while.
