Nobody know ?

What I do when I'm adding or changing a projectile is just copy a projectile (all of its data) that is close to what I want. Then I paste it at the top or bottom of descr_projectile.txt, so it's easy to find. Then you also have to rename it (if this projectile is intended for English troops, I put english_projectile_name).
