It has been decades but I think that may be a sabot round with a tungsten penetrator.
Legend has it that it punches an entry hole, travels through everything in its path, punches an exit hole possibly sucking parts of crewmen out when it leaves. |

Yes. A sabot round, APFSDS, armor piercing, fin stabilized discarding sabot.
Americans use uranium. Most other countries use tungsten. The canister round on the right is awesome! Turns your tank into a giant shotgun.

That's pretty freaking awesome, OP. So, the round goes all the way down to the primer? How does that work? Does the primer push the sabot out a bit before it ignites the powder? And how did they pack all that powder in there? Very cool round and cut-away.

Also the case combusts, so everything north of the silver baseplate is leaving the vehicle. After firing, the sabot components strip away leaving the center dart to make sweet love to it's target at about 1 mile per second. |

For those that don't know, we use depleted uranium partially because it's stupid dense and makes a fantastic penetrator but also because uranium is a pyrophoric metal. Pyrophoric metals combust spontaneously in contact with air. DU has a self-ignition temp of around 600-700 degrees which it easily reaches from the impact and the subsequent penetration of heavy armor. Meaning, that after it's penetrated the first wall of the target the DU penetrator itself is then in a highly particulated phase and it catches fire spontaneously and vigorously which creates a ball of fire inside the target that's something on the order of 5000deg F along with the concomitant pressure increase and vaporizing of flesh and then the tank turret launches 150 feet into the air. So our penetrators don't just poke holes in targets and kill the occupants with simple spall, they blow the absolute shit out of them and leave the crews looking like overcooked bacon.

While DU can burn, its not lifting turrets all on its own.
As the Brits noted in their testing of DU, they recovered 80% of the material. The rested turned into non-recoverable dust or burned.  Depleted Uranium Firings West Cumbria You'll get some over pressure/heat, but the significant portion of damage is still from penetration. You also don't need DU to get significant pressure and fragmentation, you can make hollow core tungsten rounds that fragment greatly.

M829A3 sabot round. Depleted uranium penetrating rod. DU is pyrophoric and self sharpening.
Turrets blow off from exploding ammunition of the target tank, not the sabot round. ETA: crewman getting sucked out the exit hole is a myth.  ETA2: If you look at the different versions of the M829 round, you'll see the penetrating rod gets increasingly longer to increase the sectional density and penetration capability. |
