Are you trying to make power factor for competition, or just get any reasonable load?
If you don't have to make power factor, just start in the middle of the lead data, or near the bottom of jacketed data, and work up until your gun cycles reliably.
By the way, Unique under 115gr plated is going to give you a low pressure, dirty load. HP 38 or Titegroup will use less powder and leave less residue, as the pressure will be higher. Your choice.

Added: DO NOT use any listed max loads for jacketed bullets when loading plated bullets, such as the Alliant load you show.
