"Sofft pointed tumble( I think) and have good penetration"
This is incorrect. The only bullets that are designed to intentionally tumble are certain types of FMJ military types.
Actually, this is incorrect. ALL bullets that are longer than they are wide will tumble, if they penetrate enough. This is most pronounced and most easily SEEN in some FMJ RIFLE bullets.
What differs is how much distance through flesh the bullet has to travel before the tumble becomes enough to see.
All the "classic" military FMJs in .30/8mm calibers will tumble, BUT the amount of tissue they will go through before starting to tumble is more than the average human, so the effect was seldom noted. "Yaw" is the start of a tumble.
The famous "tumbling" 5.56mm slugs got famous because they noticeably tumbled within the distance of the average human body.
Remember what bullets are. Essentially a cylinder, with a pointed end. The back end is the heavy end (the longer more pointed the nose, the more pronounced the effect) so as soon as the rotational stability is compromised (by hitting something) the upset gets worse, and eventually the bullet will swap ends (tumble).
Note how the famous "dangerous game" bullets are not very pointed. In fact, most of them are as close to a flat point as practical (within caliber range). Part of the reason is for shock but another part is to resist (or delay) the tumble taking over until after some FEET of flesh has been penetrated.
If you might need to shoot a water buffalo the long way, you don't want tumbling or expansion reducing penetration. On the other hand, when you are shooting a double handspan thick human, and your bullet has more than enough penetration already, tumbling isn't a drawback and can increase effectiveness in the target.
