You couldn't possibly shoot enough shells (lead shot) in your lifetime to have any measurable effect on the barrel wall thickness. Cleaning the barrels with a brass brush would be more abrasive than shooting it. The internal parts of the receiver will be trashed from use long before there is any neglible wear to the bore.

Too much of any kind of filler on top of a shot column can have the potentially unwanted effect of opening or blowing a pattern.
