It works the same way with slugs. Some guns prefer one brand over the other. It can make an incredible difference. But at 25 yards it is off the paper most of the time. The same gun will shoot another brand of buckshot like a rifle at room range and have only an 18-inch pattern at 25 yards.
Few shooters understand the fickle behavior of the shotgun with various loads.
When it comes to any serious concern of liability, the shotgun again is king. A 00 buckshot pellet has a potential lethal range of 600 yards at most. A 9mm bullet can kill out to 1800 yards. Sounds good but doesn't fly in reality. If we are responsible for those projectiles I would rather be responsible for them at 600 yards than 1800.
