I'm not seeing why the .357 is considerably better from the standpoint of sectional density

the 357 sig 125g is moving on along at about 1400 FPS and some folks pushing this up into the 1500+ range
the 40's 155g makes right around 1150.
Velocity means something when your interested in seeing things pulverized
