Thx for the reference to Pocket Predator.... They do have some very nice slingshots. I might even buy one, you never know. I think I like their Ranger Recurve. I had a lot of fun with them when I was a kid. I can't remember the name of the one that we all had... it was small... some sort of metal frame, but when I do a search on Amazon, they don't come up so they are probably history.Another low-energy choice for ammo is clay. Even lower: chickpeas. I get clay balls from Pocket Predator. They have some good slingshots as well.
