Except your shorter OAL is adding about 50fps or several 1000psi which is just like adding powder. Gun dims can also play a part in pressures. tighter bore, longer lead, larger chamber, it's why guns give diff results, but you know that.
"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".
