I found your answer interesting... I've spent weeks at a time in the Alaskan bush, hunting moose, big bears, caribou and even Dall sheep, living out of a 3 man tent on the Alaska Peninsula, Kodiak island and islands around it, also other temperate rain forest area's... Some times by my self, even in the winter...
I'm just wondering, does any of those hunts sound "extreme" to you?
And to think, I never have owned "the best clothing in the world"! But I stayed warn and dry and had a GREAT time...
I also have some custom guns, including from Krieghoff and NULA, but my brown bear rifle to crawl through the alders with, is a Remington 700! (yes i've harvested brown bears with it) It's put plenty of moose, deer, caribou and other big game in my freezer, so I guess I screwed up with THAT choice too! lol
Well, I DID use "custom" reloaded ammo that I loaded myself and in some cases, I also used "custom" bonded core bullets, that I also swaged myself... SO, perhaps I did some things right... (in your eyes)
