Bullets behave differently at different ranges and with different shot placements. If there is the luxury of an unhurried shot at a standing animal you can place the mono metal bullet through bone or the soft bullet through lung tissue at close range to get the desired wound channel and maybe even the desired exit wound.
Sometimes, one hunts of a life time, by the time you have stalked the critter, he has moved, or maybe while you are stalking one animal you jump another even bigger animal. Then, you might have a 50 yard shot at an animal going like hell through timber, and you are doing well to hit him somewhere in the front half, or the animal is a quarter of a mile looking at you for a few seconds and you have a front on shot where you have to drive a bullet through the front shoulder to get to the vitals.
My own very meager experience and all the anecdotal evidence that I have ever heard or seen points to the Partition as being one of the best if not neck and neck with the best bullet to bet on as getting the job done.
