i have been watching some of these life in alaska shows on tv and i notice that some use 223 ar-15 style rifles for hunting they seem to work well.
There is a reason the Natives use 223s, the same reason they used the 308, and '06 before that, that's because that is what the National Guard uses.
They are normally a "hunter-gathers society. Many don't have an income except their guard drill checks. So they supplement their ammo supplies by getting ammo from the Guard.
