On extended back country adventures, a rifle that can be field stripped without the need of specialized tools has a significant advantage over the others . In this respect, bolt actions similar to the 98 Mauser are attractive. Some examples include current CZ 550s, Brno ZKK 601, 600, and 602 rifles, older Brno ZG-47s, Winchester M-70s, and Ruger's CRF models. On extended trips, rifles that have iron sights are a step ahead of those that don't, although a second scope in QD rings can be carried in a pack.
There are few rifles nicer to carry than a traditional lever action, but IMHO, their disadvantages outweigh their primary advantage. Their chamberings are not in the class of modern hunting cartridges, and range is limited to 150 yards or so. Then there is the question of fragility, both the tang and the magazine tube are subject to damage if the rifle is dropped. Should the rifle get dropped into mud, the traditional lever actions do not lend themselves to detailed disassembly in the field.
The lighter the rifle is, the less fatiguing it is to carry, but the greater felt recoil will be. Cartridge choice should be based on two factors, the size of the game you are likely to shoot, and your ability to handle recoil. Typically .30/06 class cartridges provide sufficient terminal performance, reasonably flat trajectory, and manageable recoil. This is true for many novice riflemen shooting 9 pound rifles, however, the uninitiated will find a 6 pound .30/06 rifle, with a hard butt plate a bear to shoot. If you can shrug off the recoil from a .30/06, a .300 magnum might be a better choice for you, but if a .30/06 proves to be too much of a good thing, consider a .270, if a .270 is too much, consider a 6.5X55. I do not consider a 7.62X39 cartridge suitable for use as a general purpose cartridge in the Yukon. To suggest a 7.62X39 is the equivalent of a .30/06 at 200 yards is not something I'd agree with, but even if it were true, where does that leave you when you're be faced with a 250 yard shot? Choose a full sized cartridge that will drive a moderately heavy for caliber bullet faster than 2500 fps.
An intelligent cartridge choice, the correct length of pull for your build and dress, and having sufficient eye relief between you and the scope's ocular are the best ways to mitigate recoil. Use caution if you intend to shorten the length of the barrel, as even small changes have a direct affect on balance, more so it appears than shortening the LOP; balance is more important to gun handling than weight.
Variable power scopes can enhance the versatility of your rifle, but they tend to have longer eye pieces, so sometimes lead to challenges when mounting with the correct eye relief, particularly if you use a stock with a reduced LOP. If you think you can outrun the scope when the rifle fires, your marksmanship will be poor and there is a scar in your future. A Picatinny rail provides the greatest latitude for ring placement on the rifle. An additional factor to consider when mounting your scope is the height of the rings. The scope should align with your eye when you face is indexed with firm contact on the comb of the stock. Consistent placement of your face on the stock is essential to good marksmanship. If you have to mash you face down hard on the comb, every time the rifle recoils, you will receive a nasty bump on the cheek bone that will rattle your fillings. Conversely, if the scope is mounted so high that you have to balance your chin on the comb, your shooting will suffer.
