I've been messing around with 147 gr lead flat points for 9mm. I've been using Unique and Win 231 powders , but I haven't been able to get the accuracy and consistency that I have with my 125 gr lrn or lfp loads.

So, my question for those of you who load 147 gr lead in 9mm, is what are the powders and "pet loads" that you guys have had the best success with?
I've looked in the manuals and I know every gun is different, but I'm sure you guys all have your favorites. Thanks in advance.
