Hey gun nerds rather unrelated question. 9mm standard pistol bullet’s case is not much bigger than its bullet diameter. But rifle bullets and bullets in this picture have a diameter increase beyond bullet. Why? Why they don’t just make the bullet cases longer to store same amount of gunpowder?

Case shape funnels the explosion through a smaller area, allowing them to achieve more force with a smaller amount of powder.
Maybe to ease extraction? Standard bolt action rifles have much differing action
