Awesome thread ,I love ancient weapons. I go to be a pretty good slinger in my youth. I could send a stone in the direction I wanted pretty well. One thing i remember is you should not try to throw hard but just lob it as it will still go pretty fast. lead shot would have been way better than rocks as well.
Archery is also very cool and i have a decent smaller compound bow. I need to get out and use it more.
