I liked the part where they dropped a caribo in its track at about 150 yards with a .223. Just bang-flop. I'm using way to much gun on these desert mulies it turns out.
Actually I have a Inuit cousin.His big Rifle is a 223.He uses it for Caribou and Walrus.Pretty much does the job.
Works on flocks of geese on the wing, too. I saw a guy 'subsistence hunting' with one. Emptied it at a flock overhead. Got one, too. 1 for 30 ain't bad...
