Anyone have a WASP Target Master Keyring and can give their thoughts on it. I know it says 50% smaller but does someone have size comparison pictures? I think this would make an excellent everyday carry type slingshot to have fun with while exploring. What size ammo do you think you could shoot out of this? I know it is small but could you run 3/8s through it? Really looking for a small/slim pocketable slingshot I could throw in my pocket when I am out.
