I have shot elk with 80gr. of Clear Shot and 348gr. Powerbelt, 90gr. Black Mag'3 and 300gr. Hornady SST, 90gr. Black Mag'3 and 295gr. Powerbelt and all shots went completely through the chest cavity (none hit major bone but took out ribs). These shots were at about 80 to 110 yards. Why would you want more power????
