Can we talk about practical use of Slingshots for hunting or other /out/ activities?

I used to use them all the time growing up around the yard when I wasn't out of the town to use a firearm. Even used them when I was in my teens to knock birds out of trees because I was such a huge rebel...

Now I'm looking at picking up the Survival Slingshot to add to my arsenal for Small Game hunting (already have a .22, shotgun, and bow with thumper arrows) and also to take with me when I go out camping on public land.

Anyone have experience with slingshots?
