Hi im new here, name's Paul.

I was reading alot about clay balls and wondering if you mean small balls you made then fired them or just raw clay made into a ball and letting it dry?

Hi Paul and Yurek, I find clay missils so good and their main feature is than you can shape them as you want, with good ballistic features. They are better if only dried at sun, as they are heavier than beaked ones because of the water retained. Stones are better  if they have the appropiate shape, but is more difficult and each stone are lightly diferent in weight and shape even if selected. Clay balls can be standardize and this is the advantage that made them de war missils in antiquity, before lead missils.
The clay must contain a proportion of sand to be shock resistant, and if you don´t shoot against rocks or walls, you can reuse the missils.

Welcome Paul,

I used clay projectiles for quickly testing projectile shapes.  You can read about it in the articles section, Titled "Roman glandes, projectile tests".
