First, check at least two sources and START at the lowest STARTING load.
Second, thin plated bullets like Rainier and Berry's should be loaded like lead.
Third, you should take at least 10% off the jacketed starting load for your starting load.
Fourth, do not go to a MAX load unless you have worked up to it and it shows no pressure signs in your gun.
Below is a compilation of load date. One is for 115gn jacketed bullets. I don't have ANY lead loads for 115gn bullets and Universal.
Based on the jacketed data, I would start at 3.6-4.0 gn. Based on lead bullet data for a heavier bullet, I would start at 4.0gn (1/10 higher than the data for a heavier bullet) and work up to 4.5gn. I would not load a thin-plated bullet up to max 9x19 velocities and would be looking for accuracy and, if needed, a given power factor.
