What I've done is copy an existing projectile, then mod it.
For example, find the Iron Arrow in CK, then open it up and check the other CK files it references (there is a file that describes the object, and other that describes it's properties like flight physics, dmg, etc). Make duplicates of these files and change the references accordingly.
I don't have a good handle on how to replace the models (the appearance), but those references are also listed there as properties.
