One modern powder that fits that description would be vihtavuori n340 and the faster-burning n320. And yes there is some limited load data, if you search for it. Both of those powders are porous, extruded single-base

Certainly other powders can be used for 16-gauge loads and personally I reserve my stock of 7625 for heavy 12 and 10-gauge loads. Me, if I needed any 7625 I wouldn't balk at $50. per pound.
