I went through a similar thought process when I started reloading .40S&W and saw how much of the case was occupied by a 180gr bullet. Well, actually, I first got thinking in that direction when I noticed notably stronger recoil from Fiocchi 165gr JHP than from the Fed Champion 180gr FMJ. But then, I shot some Rem 180gr JHP, and it also produced a stronger recoil.
On the other hand, Hodgdon is comfortable quoting 1159 fps for the 180gr XTP driven by 8gr of Longshot at 1.125" COAL at 32,300 psi.
He that dasheth in pieces is come up before thy face: keep the munition, watch the way, make thy loins strong, fortify thy power mightily.
