    You're gonna need some old manuals. It was replaced by W231. The data is not interchangeable. And the internet rumors about why it was replaced by W231 are quite interesting.

    I did a little research and looks like it was used in 45 acp. I have a lot of unique but it doesn't meter well in my rcbs powder dump when it get down around 3-4 grains. I want a good metering powder for my 9mm and was hoping ths 230p would work.

    You are welcome. There is data for Win 230 in Hornady Vol II but don't know difference between 230 and 230P, from the data shown it looks like Win 230 is faster by a good bit, max load with 125 Horn HP is 3.8 grs
