Edit: To answer your post more directly: The reason for your being unable to throw the lead as far as the baseball is because you're unable to achieve the same velocity with the heavy object as with the light. If you could, the lead would go farther than the baseball.

You need to have a chat with Galileo or Newton.

If the lead ball and the baseball are the same size and shape, and are launched with the same velocity, they will travel the same distance.

The reason the feather falls more slowly is due to air resistance.
