Modern Reloading, 2nd Edition, by Richard Lee, has plated bullet data
For the 115gr 9mm, it does not have data for Unique. However, it has data for several Vihta Vuori powders and for Accurate #2, #5, and #7.
There is no VV data for jacketed 115gr bullets, but for Accurate #5 and #7, the MAXIMUM loads for the plated are lower than the STARTING load for the jacketed. With #2, the loads are 0.1 gr less for plated, but the muzzle velocities are a little higher.
