Yes, shooting BBs is an excellent and inexpensive way to hone your technique.
BBs can be shot from any slingshot with the appropriate bands. The key with BBs is not to overpower the projectile.
Ultra lightweight bands and a pouch made to shoot BBs are required. Simple Shot offers dedicated BB band sets and slingshots. Our BB flatbands are made from SimpleShot Premium Black latex and are perfectly powered to shoot tiny ammo!
