Need load data for .45ACP 185-gr FP and Win-231

[IMtheNRA]

I have a 100-pack of gunshow mystery bullets. Copper plated, 185-gr, Flat Point. My only manuals are Speer-13 and Hornady -7 and neither lists a plated bullet. What's more, their data for jacketed 185-grain FP bullets differs by a significant margin. If I load these, I'll be shooting them from a Glock-21-C. The only pistol powder I have is Winchester-231.

Does anyone use similar bullets with Win-231? If so, would you mind posting your load data for light to medium versions?

Start with 6.0 Grains and work up. Should be light. 800 FPS or so. Midways Load Map for .45 shows up to 7.5 with the old Midway 185 gr. plated bullet before it gets in the red zone.

Walkalong's data is good--but if you want a lighter load, you could start at 5.6 gr.
