So, my wife and I were talking about our kid and when he was allowed to have a slingshot, and it occured to us that a good portion of the damage potential depends on the ammo used. So, I'm looking around through Google to see if Nerf or something similar has a foam ball that's a good size for slingshot ammo, but I thought I'd ask you guys about it. My son is only three, but I intend to have a light band set and ammo in mind before he's of age so that when he does get interested in shooting slingshots like Daddy, I can give him something to learn to shoot safely on, rather than telling him, "Too bad, you aren't old enough, now stand over there while Daddy has fun with slingshots"<br><br>I'm hoping for something that is at least sort of around the same size as normal slingshot ammo, though I'm sure foam balls will be bigger. Maybe 20-25 mm or so? We'll see what I find. I intend to do a series of tests with ammo / bandset configurations once I have some contenders, unless of course there is data out there about it already.
