How many pounds of ground beef is needed to make 600 meatballs?

I need more information to answer that! Tell me:

* How big are the meatballs? Are they small cocktail meatballs, or large dinner meatballs?

* What is the recipe you are using? Some recipes use more meat per meatball than others.

Once I have that information, I can help you calculate how much ground beef you need.
