Potato “patato”. or 6 half dozen. I have used both and to me both are great choices…which can you source given supply drives my decision between these twoEither bullet will easily exit both animals and there is a real possibility of hitting animals beyond that. There's not much that can stop a 500J premium bullet...certain angles on ele, rhino and hippo, maybe. I've got some of both bullets but the A-frames are not easily sourced in general. If you can get either bullet and it shoots well enough for you, there isn't a bad choice. I would happily use either bullet for any DG except where solids are needed.
I really like the TSX for buff. I haven't recovered a bullet yet and the buff definitely react to getting hit with one. Recoveries have been very quick...right there or very quickly within sight. Of course, shot placement is #1.I think the TSX is the ultimate cape buffalo bullet. Never hunted brown bear so can't speak for that
