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.
"Given adequate penetration, a larger diameter bullet will have an edge in wounding effectiveness. It will damage a blood vessel the smaller projectile barely misses. The larger permanent cavity may lead to faster blood loss. Although such an edge clearly exists, its significance cannot be quantified".
