Think you are trying to put a saddle on a race horse.
The key to reliable expansion is velocity and you probably need more powder capacity to achieve the velocity necessary to have a 165 grain bullet expand reliably.

You are right, but bullet design has as much to do with it. If a 'short barrel' bullet can be designed for .38 special, that expands at 800-900 fps a heavier 9mm could be made to expand at around 950 fps also
