I've used the .44 Skeeter load on wild boar with reasonable success. No "bangflops", but I prefer non-expanding bullets and I go for reliable shots rather than spectacular ones. That generally means trying to put a bullet through both shoulders.
I have not hunted big game with the .357 Magnum. I have thought about it for decades, but just don't quite have the confidence in it. With solids, the hole just isn't as big as I'd like, and with JHPs the penetration isn't there, at least for less-than-perfect presentations. And yes, I know the grand old cartridge has been successfully used countless times, even by Skeeter himself.
At this point, I'm unlikely to ever try big game hunting with the .357 Magnum. If I do, it will be with a 158 JHP driven as hard as the gun will take, and the shot will be broadside into the lungs.
