without getting too specific.....the projectile is designed to "tumble", or "spin" upon impact to create maximum damage, and so as to not go through the body (because of its speed) without little damage.

It's not the firearm that causes the round to tumble. The .223 is just like any other rifle round where the rifling on the inside of the barrel causes the round to spin. The increased stability means longer range and better accuracy.

The round tumbles when it hits an object, the reason being a pocket of air left in the nose of the bullet. The nose collapses, the bullet destabilizes, and rips itself apart as it travels through an object.

None that I'm aware of. In fact, a tumbling round is nearly worthless, as I understand it, since rotation on several axis would cause the bullet to go out of control and end up far outside its desired trajectory. Aiming would be worthless.

The reason rifled bores were employed to replace smooth bores was because a spiraling round maintains its balance and accuracy over a far longer distance. A round that tumbles on its way to the target is antithetical to that end.

If the rifling isn't "fast" enough for the bullet weight, it is highly unstable & will tumble when it hits ANYTHING. Or the projectile can be specially designed to tumble - see 836
