Put simply: horizontal components of projectile motion act independantly of vertical components.

Air resistance doesn't vary with weight or density. However, the lead ball still hits first.

Ummm... Not neccessairly. I was thinking of the myth of dropping a penny off the empire state building. The wind from the top of the building actually forces the penny to the side of building thus slowing it down. Im not sure how it would affect a larger object such as a ball but if it is strong enough to forceit up against the building then yes it will have an effect.
