I can't speak for your specific set up but I use Winchester 231 powder for my pistol loading. I really like it, very consistent when using an auto type dispenser. I don't get off more than .1 from my loads. I think that is pretty accurate but I am no expert. I like 231 because the min to max range is pretty high so if a min is 5.4 and the max is 6.2 if your dispenser is set at say 5.6 I am never off by more than.1 5.5-5.7. I am pleased with that result.
Not sure if I helped but I can not give an opinion, I am an American.
