Yes and that's still a case volume capacity improvement. More space, more powder, higher velocity achieved. .

Absolutely, as long as you have the correct powder to do it.
Without that vital component, the ballistics fall short of the actual potential.

When a case is oversized to the bore, for the powders in use for it, it's ballistics suffer compared to smaller cases with appropriate powder for them. By "suffer", I am saying that smaller, more efficient cases can approach the ballistics of the larger case & they do.

The larger the case for a given bore size, the less efficient it is in the amount of increase in fps compared to the grains of powder weight it needs to produce top speeds.

Barrel length also comes into the equation.
