Go to office max or somewhere, Look for #64 or 117Bs. can be cut to suit the little guys needs.Long office rubber bands so they won't be too strong. You want a light set up for your Lil poke master. I don't normally shoot office rubber bands, but there are guys here that do and use them for tiny bbs. They will chime in and give you more ideas on light set ups.Thanks so much for the great idea covert5. Will be picking up rival ammo this evening. What exactly do you mean office rubber? I'm new to homemade slingshots lol.
