The thing about lead is it is either a hassle or it is not. Generally it is not somewhere in between. If you gun has the proper barrel diameter and your don't mind you gun getting dirtier than lead is an excellent way to save money. If your gun has an oversized bore lead will give you all sorts of problems.
Most people who shoot commercial hard cast lead will have leading to some degree. They are made with a "one size fits most" mentality and are generally harder than they need to be. I've never had a problem scrubbing out leading with a copper brush and some lead solvent.
New gun, same ol' shot.
