With your slingshot in hand it’s time to head to the river and draw out your five smooth stones. But perhaps you don’t live near a creek where such ammo is bountiful? Or perhaps your hand finds the course texture of the rock unappealing. Our solution, Marble Ammo. Our Marble Ball Slingshot Ammo pack is a compact bag of roughly 25 smooth, 5/8th inch marble balls made to fit perfectly in our Leather Ammo Pouch. These glass spheres mean business and paired with the right slingshot can provide excellent assistance in your next small game hunt or bottle demolition. Just remember to shoot responsibly and adventure well.
