My idea isn't zactly like anyone else's. All my rifles are tools. But you won't make much making tools.
As we have multiple seasons open at the same time . The 243 is hard to beat. Since we can use fmj bullets it's not a problem destroying fox or lynx hides . And the 80 gr TTSX will work on caribou and wolf. I like the thumbhole laminated stock. More torsional strength for those times we find ourselves under instead of on top of our snowgos or 4,6 wheelers.
If a 223 is picked then it should be a 1 in 7 twist so it will make the 70 gr TSX and the 75 gr Sirrocco behave. 24" barrel on either Cal of a palms contour. Of course the action must be a Ruger stainless and if a 223 it should be set up for ar 15 mags and if the 243 then for ar 10 mags.
For a trigger a Spec Teck stainless adjustable to 2 lbs . The inside of the bolt needs to be treated with something super slippery and permanent so the firring system can be totally degreased for the cold and not gall. As most shooting is done from a seated or standing position the comb hight shoould be high enough, but not as high as a dedicated prone rifle. Foreend should be oval and in the 2-21/2" width and the length sould of the foreend should be a flat plane to help keep it from sliding around as much on a snogo seat or 4 Wheeler handle bar. . The barrel and action should be CerraKoted in a color that looks like a dead tree limb. Tan, light brown, dirty grey color. Stock the same. Like a brown, tan laminate. Grip and fore end should be checkered with a good deep, sharp checkering. Should weigh 8.5 lbs before scope and magazine.
But, that's just my idea. Doesn't need a muzzle brake
as mostly all it will do is blow snow around and help give away your position to the pack or heard if you get into one.
