More expansion is nice but the diff really is getting a bullet to crush tissue & not just push it aside. Given that RNFMJ are like making small, semi sealing puncture wounds, I would take a 9mm that only expands to 45 cal vs a 45 RNFMJ. The perm wound will be larger, damage more tissue, greater/faster blood loss, quicker end to the fight.
