Hi, anyone used either on cape buffalo or other dangerous game? I've only shot a 450 lb. feral hog at 8 feet with my 500 Jeffery so far. A 570g TSX at 2300 fps between the eyes penetrated the length of his body and liquified his insides, but that's just fun not a real test. I'm loading both TSX's and A-Frames at the moment, both shoot real well at 2300 fps.
