Yes, I have been buying it in quite large amounts and getting a good price but my days of buying steel ball ammo is really over as I just counted up last night what I have and I don't think I can use up what I have in my lifetime.What @wll said . . . look up "steel ball slingshot ammo" in the size you want. Usually described as "carbon steel" or "utility grade carbon steel". Also usually is the cheapest grade. Should sell for around 1.5 to 2 cents per round if you buy in bulk (1000 rounds).
