I use Win 231 for everything from 380 to 45 LC. It will work but no where near the best for all.
For the 9mm to 45CP it’s by far my favorite for target and plinking loads. Using one powder for all you’re never going to get the highest velocity or accuracy but you can get good results.
I load all of my handguns with 5 different powders.
There should be a burn rate from slowest for fastest in your manual its this burn rate that makes some difference. But the big thing is that it’s all about pressure. The powder loads given in manuals are tested and are safe for SAMMI pressures. Going above that point and your building a possible bomb.

If you need more data for W231
