You will likely get tired of humping two guns around in he bush, the last thing I want to do while hunting is have a grizzly in my hands and my hunting rifle in a scabbard. Then again my hunting rifle is chambered in .303 Brit and if a bear came into the pic it would be adequate as long as I can put it on target, if I'm walking or sitting it's got a round in the chamber and 9 more in the magazine with the safety on.
Weight is always a factor when out hiking or hunting, pack+2 guns is a lot more than I want to carry around unless one is a pistol and we all know that isn't happening for most joes in the bush.
Yeah would love to be able to carry a pistol, unfortunately ill have to settle for a short shotty unless the CPC gets in and goes to town on repealing our current gun laws.
One gun would be ideal, and my hunting rifle is a .308 so will handle a bear. But its not a thick brush or rough terrain gun, in those instances ill be carrying the shotty and have the bolt gun stashed away, same as when im skinning/gutting my animal, better to have the shorter/handier gun handy for those situation IMO. And im not young, im lazy, i dont stray that far from my truck. weight of my pack/gear is not as relevant as if i was covering alot of ground.
