Never likely to hunt Africa, have seen what my bullets do on black bear and a decent interior grizzly bear (friend shootingmy bullets in a midrange454). I think if I were to tackle grizzly, I would definitely want the heavier bullet, it broke bone and penetrated over 3ft. A large bovine, I think I would prefer a Punch style solid. Just wondered if anyone had used the 285gr SWC on elk sized game?
