You don't get those nice and perfect gel flowers in real flesh. Those gel flowers are produced to sell ammo.The theory that expansion is overrated represented in a picture.
In that theory whether the bullet (in the center) expands is less important than shot placement, amiright.

However, there is no way to guarantee shot placement.
With less than optimal shot placement, the increased diameter of one of those expanded bullets might hit something important.
Given the same shot placement, bigger holes are better. IMO.
