Watch out for the S&W, their revolvers cannot keep up with ruger and lever rifles. If the ammo says its ok, then it should be ok, but some manufacturers will load up to ruger only levels.
I loaded up some 360 grainers in the LC, which were listed ruger only that are getting pretty close to the .454. (Only three grains less powder on the max load)
For .45LC in Alaska, you just have to make sure they have the boom. There are some 300grn cowboy loads out there that aren't loaded like they should be. (Well, like they should be for bears)
