I'm loading 5.5 grs Unique under a 124 gr Golden Sabre. It shoots extremely good out of all of my 9mms. You'll find OAL on the 9mm critical for accuracy. Mine are loaded to 1.130 but you are using the Berrys so it will be different. Pick a load of a favorite powder, do not go below recommended OAL but you can go longer in .010 increments. You find the sweet spot for your pistol by loading this way. After that, any loads that you develop, you can start at the sweet spot for the OAL as long as it isn't shorter than the recommended OAL. Considering you are using Bullseye and Rainier bullets are pretty close to the Berrys in profile, Rainier loading data calls for a max load of 3.9 grs Bullseye and OAL 1.169 which is max length. I'd be loading something like 3.5 to 3.7 grs Bullseye and play with the OAL starting at 1.110. FWIW, Hornaday shows a max load at 4.4 grs Bullseye so the pressure spike will not be an issue with going shorter than 1.169.
