3/8" Steel Slingshot Ammo

About 3/8" Steel Ammo

Pour out a bottle of 3/8" steel and you're holding the round most slingshot shooters trust, and the one we recommend. These are precision steel ball bearings, uniform in weight and shape, which is exactly what accuracy needs. Round ammo flies true; out-of-round ammo doesn't. With steel, every shot leaves the pouch the same way.

3/8" is the everyday standard. It balances speed, power, and easy-to-find bands, which is why most shooters land here. New to it? This is the size to start with.

Steel is endlessly reusable. Fire it into a catch box, scoop the same rounds up, drop them back in the bottle, and keep shooting — a single bottle lasts a long, long time.

A note on shipping: steel ammo is available in North America only, since its weight makes overseas shipping impractical.

Counts & Reuse

Steel ammo ships in reusable poly bottles, so you can refill as you go:

• Sample size: about 85 rounds, perfect for trying it
• Full bottle: about 345 rounds for regular shooting
• Reusable: fire it into a catch box and the same rounds load right back up

Grab a sample to feel it out, then keep a bottle on the bench.

Why Choose 3/8" Steel

Our pick for accuracy. Consistent steel balls fly the same way every shot, so your groups come down to your form, not your ammo.

The everyday standard. 3/8" is the size most shooters shoot and the easiest to match with bands. A safe place to start and a great place to stay.

Reuse it again and again. Fire it into a catch box and load the same rounds right back up. One bottle goes a long way.

Does it all. From backyard plinking to target practice and training, 3/8" handles the everyday shooting most people do.
