My stainless one weighs 3lbs 12oz, with 20’ of paracord on the barrels, just checked.
That's a big difference from what google says. I still don't get the appeal, 12 oz is 100 shells for the Savage Rascal. My idea of a "survival" gun would be a folding or takedown, short barrelled 12 guage, either single shot or over/under. Some birdshot, a few slugs, and some flares for signalling that can be used with an open choke.
Four 410 shells seems little better than zero 410 shells to me, it would by necessity be used on stationary targets, I spent enough time on the trap range during waterfowl season to have no faith whatsoever in the ability of Joe Average to hit a moving target.
I went down the combo gun road for farm and wandering use and found it wanting, not accurate enough with the rifle and awkward with the shotgun.
I still think the very idea of military personnel foraging for food after a crash is fantasy, a Nazi Belt Buckle pistol is arguable more useful. I have in my hands an RCAF Pilot's Logbook, it includes searches for missing planes, there is no indication that any had a happy ending, for example, one entry says " Found Capt ###XX, killed, plane burned". and these weren't Starfighters hitting the ground at Mach 2.
Stranded I can see the utility, crashing I see little, four grouse are not going to materially change the outcome.
For exploring:
The Shackleton Antarctic Expedition took a 12 gauge and a 318.
The Morden-Clark Asiatic Expedition took three 1903 Springfields, a Marbles Game Getter similar in concept to the M6, "Used Rarely" the notes say, the 1911 was "Never Used", and the Colt Woodsmen was "Almost never used".
Naomi Uemura went solo to the North Pole, he took a 303 ( and killed a camp raiding Polar Bear with it) after the Canadian Govt in it's wisdom wouldn't let him take a 44 mag handgun (to the North Pole FFS!). My father got National Geographic back when it was good and I remember this article well.
But, the OP says he plans on moving to the Yukon or NWT, this means he needs a moose rifle. The grizzlies are supposed to be the smallest extant in North America, a 270 WCF would likely work well, it was a "big gun" before the internet when Grizzly and Moose tags were over the counter.
Lightweight, rugged, open sighted (best be in camp before dark in unfamiliar country), powerful enough for moose. Really the stores and EE are full of guns like this, but this is a gun forum. In my mind, the choices would start with the 6.5x55 and end with the 300 Win Mag.
I get a kick out of the Ruger Gunsite Scout, junk hanging off of it, the Ruger 77 reminds me of the Yugo Mauser, it may work, but its fairly crude. I'd take a pre 64 Win 94 over the Ruger GSS any day. Compare a Ruger to a Yugo Mauser, then to an early war or pre war German Mauser, they aren't even close. This isn't even considering the questionable ballistics from the short barrel, people think they're powerful because of the muzzle blast. I had a girlfriend that started crying the first time she fired my FR8. The only reason to ever pick a 308 is the Savage 99. The 30-06 is better in every way. The 308 is like the M6, some strange idea that somebody in the military had., it was only 60 years out of date when adopted.
Get a Husqvarna 30-06 (or 8x57 if you reload) from Tradeex. Buy a good pair of binoculars.
