Powerbelts seem to be one of those projectiles that people like or hate. I have a CVA Staghorn Magnum 209 and it will shoot powerbelts with outstanding accuracy. Unfortunately the deer would not cooperate with me this year to test the powerbelt theory....
Most of the post I read, the aero tips get excellent penetration, while the hollow points tend to hit, open and are usually found on the far side of the animal from the wound. Many report extensive damage from the hollow point but many report little or no blood trails.
Congratulations on the deer.
