I think the bullets would need to be .355". I tried my loaded round in a 9mm case gauge and it would go in with a little push. It would completely seat in the chamber of my 9mm LCR with a little push. The bullet wouldn't need to be seated any deeper than my sample. I think the fact that my bullet is .358" kept it from chambering easily. The 9mm throat kept it from fitting easily.
Tomorrow I'll load a few and try to shoot them.
