Prolong the life of your slingshot with this specially selected steel ammunition. Not too small, and not too large, this ammunition is designed to provide a good balance. Ammunition which is larger is unwieldy and can be unsafe, while ammunition smaller can tear up sling bands. This 5/16 inch ammo is perfect for your wrist-braced slingshot. Unlike cheaper Grade ammunition which often has flat spots, this premium ammo is perfectly round for better accuracy.
