Don't get bitter and act like a child, someone feels like hunting dangerous game such as Buffalo or Elephant with a FMJ 338 round, his 7mm, 06 etc... good luck.
Could you kill it, yes, sure, so COULD a 22, will you stop it from stepping you into a puddle of blood, no, no you wont.
Like is said, over, and over, and over again, there is a distinction to be made between a round that, will, kill something, and a round that will stop something from erasing you.
He didn't specifically ask for a stopper, but ideally, I believe you'd have to pick it, for whichever animal you pursue. Relying on your pro hunter is dangerous at best, puts everyone at risk.
I am not even somewhat close to an expert, this is a simple internet thread that has no real intent behind it, but let us keep reality in our thoughts here.
Shoot an animal with whatever you wish, bow, 22, 7mm, 50bmg, but when you aren't prepared for the worst and it comes, don't blame the people that you put in danger.
Spears were used for years, doesn't make them ideal, or the intelligent choice, horse and buggy used to be, THE mode, of transportation, doesn't make it ideal for cross country travel in today's world.
Above and beyond all this, if you can't hit what your intended target is, then Zeus's lightning bolt wont help you.
