Am always slightly puzzled when both the Barnes TSX and Swift A-Frames are rated so highly, either by hunters or PHs. They work very differently. The A-Frames normally expand widely so don't penetrate nearly as deeply as TSX's in the same weights and caliber. In fact, in my experience would rate them at opposite ends of the spectrum as far as penetration.
That doesn't mean both aren't excellent bullets, but a number of bullets in between their differing parameters work equally well--which should be no surprise.
And the good old Nosler Partition 'may' out penetrate them both.
