The 9mm version of that bullet expands quite well-at least in tissue simulants. The velocities quoted are in the ballpark for the 9mm standard pressure load. I'd expect the load to perform about as well as the 9mm version.

Erichs brought up a very important point about +P+ .38 loads. They were ALL intended to be used in .357 Magnum guns. The whole point of the exercise was to avoid use of ammunition with the dreaded "Magnum" headstamp. This was a real big deal at the time with ACLU (and fellow travelers) who wailed about cruel and unusual punishment when Magnum ammo was used.
