If half of the people like Powerbelt and half dont - whats the point of using them. I have made a few post about my experiances with PBs and most were poor ones.
I have not really heard of anyone shooting nosler partitions and having no blood trail. I liked shockwaves and now have switched to noslers and they expand well and exit consistently.
TC shockwaves and nozler partition will shoot well, most likely, out of your gun. You should give them a try.
