I happened upon a box of military contract 9mm-147 grain Subsonic JHP so I was curious to know what that was all about. Obviously it could not be used for battlefield distribution since that would violate the rules set forth by the Hague convention of 1899. So who ordered these? I do not know.

do you have any guesses as to the type of powder (or whatever is closest commercial equivalent)?

3.8 to 4.0 cfe with xtreme 147 HP will do it.

Must be a nice, fairly soft shooting load.  Accurate?

Good question. Never did bother to shoot paper. Maybe next time.
Speed and weight is very similar to ordinary 38 special.
