I have used Trophy Bonded Bear Claws for a number of years and really like them on thick skinned or hard to kill game animals. I was fortunate enough to have known Jack Carter back when he still owned Trophy bonded Bullets. His office was here in Houston and we met through the Houston Safari Club. Back in the early 80s when we met I was looking for a tough bullet for a trip to Alaska. As our friendship grew I was allowed to test various new calibers for him before he introduced them to the market. The Bear Claws are similar in performance to the original Nosler partition design. The rear end stays intact and pushes the expanded front portion of the bullet through the animal to achieve a larger, deeper wound channel. Over the years my kids and I have used them to harvest whitetails, fallow deer, axis deer, feral hogs, gemsbok, scimitar horned Oryx, elk, moose, black bear, grizzly bear, caribou, eland, giraffe, sable, roan, sika deer, red stag, wart hog and several other types of animals. I dont think you can go wrong with them. My only reservation would be that as with the Swift A Frame, Nosler partition and other similarly constructed bullets, you dont really need them for thin skinned animals under 400 pounds.
