These have been around for a while in handguns {modern}, the theory is that the nose shape displaces tissue laterally to cause cavitation damage with out limiting penetration.
The greater the velocity the greater the effect. I have not seen many reviews on this bullet but what I have seen has been positive.

The rotation of the bullet is supposed to create a large cavity in the handgun bullet ads. Not sure that makes good hype in a slow twist muzzleloader. Also, the denser the projectile (especially the outer portion), the slower the twist needed for gyroscopic stability, so the lower density will be less stable, but speed can overcome that (faster spin at higher velocity).

Maybe I'm wrong but I thought a heavy bullet wants a faster twist as opposed to a slow twist for lighter ones?

That's generally true for conventional lead bullets when bullet weight often corresponds to its length, with heavier bullets being longer.
However, the preferred twist rate for a bullet is usually based more on the length of the bullet rather than its weight.
But in this case, being made of relatively light copper and polymer (plus a plastic base), they may need more RPM's if they're "longer bullets" for the twist.
Some bullets can also be affected by the depth of the rifling grooves, and the shape, balance and design of the bullet.
They could shoot well in some guns and not others with the same twist rate, or be dependent on the powder charge, all else being equal.
Or that nose design could be affected by air turbulence while in flight to some degree.
Who really knows without testing them in a tunnel with a bunch of different guns, powder charges and twist rates using a machine rest?
Also, that bullet is designed to rip through the hide and remove tissue so that the wound won't stop bleeding very easily.
So maybe the design has an accuracy trade-off built into it.

If anyone can figure out how to get that bullet to shoot well, he will.
