Not sure what you mean.
Slower powders spread out the peak pressure and can achieve higher velocities--depending on barrel length to let the powder do its job.
If you want more velocity, you move to slower powders, until you reach the point where the powder is too slow to achieve any velocity increase in the barrel length you have.
If you want slower target loads, you move to faster powders.
This is true for all firearms.
