Well vel alone is also just a guide. Vel varies from pistol to pistol, bbl length to bbl length, so trying to "guess" pressures by vel will get you into pressure trouble very quickly (ie, trying to get "book" vel in a G26). If the loads in farnorth's pistol are not showing pressure issues, then they are "safe" in his pistol.
"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".
