The heaviest PowerBelts at moderate velocity should work just like any other 400gr+ conical with a hollow point.
IMO the 300gr is marginal in the 50cal but not too bad in the 45cal. The lighter weights are varmint bullets.
If you want to shoot a lead bullet there are several you can buy for a fraction of the price and are good killers. Such as No Excuses or BullShops....if they will shoot well in your Wolf.
Sabots and Speer GoldDot/DeepCurl is a hard combo to beat for price and performance. PBs cost as much as TRUE premium bullets such as Barnes or Nosler Partions ect ect but dont kill nearly as well IMO.
The only good things i can say about them are: they are accurate (usually) and a follow up shot/reloading is fast because they are 1 piece and easy to load.
