Mike,
I hunt a few miles south of Red Lake Reservation. Many years I only get to hunt opening weekend, and some years it was bucks only for us. I wanted a rifle for deer, black bear, moose, and maybe an elk so I picked 35 Whelen.
Awhile back I got to hunt caribou, and the Native Alaskan kid at the Army Surplus store in Anchorage told me he hunts with a 223 Mini-14 for caribou. He hunted for the whole village.
I guess I am old fashioned but at 53 yrs old what can you expect?
Regards,
Jim
