The Yukon offers open country, and thick, steep country and flat, so where and for what comes into the equation for the best rifle, just as it does anywhere else. If one is hunting bison in thick cover, or grizzlies in the willows, a large bore diameter can be considered beneficial, even though the .30/06 180 makes the legal minimum for bison. If on the other hand Dalls are one's primary interest, a flat shooting small bore would seem to be a logical choice, and therein lies the conundrum, finding a single cartridge that adequately addresses such a broad spectrum of use. Do it all cartridges tend not to be as good at any one particular thing as niche cartridges, and the further one strays from the optimum, the less useful they become in niche situations. A medium bore size that can drive a mid-weight bullet to 2600 fps will provide the flat trajectory desirable for longish shots. It will also be available with heavy for caliber bullets that provide a sense of well being when making your way along a bison trail in the thick stuff.
A more important element than it's cartridge, should be the rifle itself. Its features should result in a light, quick handling rifle, that will not unduly result in fatigue while afield. IMHO, it should be equipped with iron sights, as well as a low powered variable power scope mounted in QD rings. In such a rifle, a big case .338 or .375 might be seen as being too much of a good thing, where a 9.3X62 or a .350 magnum is more user friendly, if you're concerned with such things. If recoil is a serious problem for you, then a .30/06 with bullet weights from flat shooting 130 gr TTSXs to bone crushing 240 gr Woodleighs has much appeal, where a .300 magnum has similar disadvantages as the big case medium bores, that being a larger, bulkier, heavier rifle, with more recoil. Again, IMHO, a bore diameter that's smaller than .30 caliber is not in the running. The all-around rifle should be one you shoot well, and to that end it must fit you, not only the LOP, but also it's comb height, and eye relief, which can be tricky in a rifle that is to be used effectively with both irons and optics, as QD rings are not available in an extended style, and not everyone appreciates a long one piece rail on a big game rifle. While I normally prefer CRF actions and fixed ejectors, the rifle I'm having built with the Yukon in mind is being configured around a 700 Remington action. If the rifle has a short forend, in an effort to reduce it's weight, placing the forward sling swivel on the radius of the forend tip will prevent a cut hand, and this sling stud location is my preference on my hard kickers as well.
A thick cover bison trail . . .
Open vistas with enough cover to conceal a grizzly or a moose until you step on him . . .
The Model 7 KS in .350 magnum is one answer chosen by Yukoners of much experience, C-FBMI's on the right was kindly lent to me . . .
More important than any other consideration though is soaking up the Yukon, which may well be the ultimate outdoor experience . . .
