Yes I have met people who have hunted feral pigs I think. In the UK it is sort of legal to hunt small game with one but not deer. I have hunted rabbits and squirrels with the atlatl but with no success.
For hunting it is best to use heavy darts with modern archery broadheads. you'll also need to be pretty damn good.

Hey man, cool vids..
Do you yourself or do you know anyone who does actual hunting with the atl-atl? (deer, elk, etc.)
