This is just me, but one of the biggest things I've learned over 3+ decades of hunting and killing elk is that I like to have 2 holes in the critter. If all goes right, many loads, guns etc will do just fine. When I'm going for serious I like to ensure that I've a load that will give me 2 holes.
The 185 TSX will do just fine most all the time, but I've seen it stopped in an elk and would prefer a bit more bullet. Until people have hunted elk and seen a lot of dead elk they just don't get what I'm talking about.
Pigs and African plains game for the most part is a very different proposition than hunting elk. Especially if the elk are on public ground.
