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?
