I am making some trim weights for my backplate, and need to make some lead shot..... instead of the mold, do I just drop the molten lead into a bucket of water?? TO form the tiny balls of lead???

Walter:You are partially correct. The reason for the drop is so it will form a sphere. Liquids dropped through the air do not immediately form spheres. You are correct in that some cooling (and hardening) is necessary for the drop to retain it's sherical shape when it hits the water.
Molten lead poured into water does not explode. It will, however, instantly vaporize some of the water which is probably what you are mistaking for an explosion.
