Wikipedia isn't a valid citable source.

Even if it were, in that same article;

"The blunderbuss could be considered an early shotgun, and served in similar roles. While various old accounts often list the blunderbuss as being loaded with various scrap iron, rocks, or wood, this would result in damage to the bore of the gun; it was typically loaded with a number of lead balls smaller than the bore diameter. Barrels were made of steel or brass."

Emphasis on "would result in damage to the bore of the gun"

Just because some people did something, doesn't make it a good idea or mean it was an intentional design feature.
