Moose with an SKS? If you're a good hunter and shoot well and impose a hard range limit on yourself; yes. 7.62x39 is very similar to 30-30, and you can get 150gr plus rounds for it (and handloads of course). The venerable 30-30 has killed more north american game than any other round, from deer to moose to grizzlies. I worked in a sporting goods store for a few years and I sold more 30-30 rounds to native big game hunters than all other calibers combined. They never felt underpowered, and they brought home tons of big game. I know two guys in the yukon who hunted exlusively with .44 magnum semi-auto rifles; and they brought home moose and grizzlies, and that's with a pistol cartridge. And lets not forget; people hunt moose with bows and arrows as well as black powder muzzle loaders. How do they do it? They know their weapon and hunt respectfully within the limitations of what their weapon can do. And they practice. The last three moose I shot were all under 100 yards and all shot right where I wanted them to be, I didn't shoot them with an SKS but I know I could have. I bought an SKS recently and put a scope on it, put a good stock on it, did a partial bedding job on it, did a trigger job on it and bought some Wolf 154 gr SP ammo and I am going to hunt with it. And I won't be wounding anything either.
