I will soon have in my hands a folding stock PPS carbine converted to 9mm NATO that I intend to gift to my son when he returns from Germany. Consequently I'm looking for some handloaders experienced with loading heavier 9mm rounds (124 grain, 147 grain) for optimum performance in a 16" barrel 9mm carbine/submachine gun. Lighter loads (115 grain) may not reliably cycle the PPS action, and if there's one thing necessary in such a platform it's reliability. I'm thinking of this as a vehicle carry piece, capable of engaging assailants in other vehicles, so I need maximum throw weight, penetration and velocity. Too bad they don't sell new or salvaged steel core projectiles anymore.
I'm looking for load data because to buy the complete rounds new would, I'm assuming, be prohibitively expensive and if there's one thing I'm low on at the moment it's ammo money. A faithful reader the other day sent me unsolicited 2000 pieces of 9mm brass, so I'd like to come up with a good load for that PPS 9mm NATO carbine (one of the project firearms that Len Savage is building). Anyone have any informed ideas about such a load optimized for the platform?
When finished it will look something like this:
