i maybe owning a 9mm pistol question??

Yes. Download a PDF copy of Lee Modern Reloading 2nd Edition from the web. You might have to search for it.

And you can always ask Alliant. They probably have data around there some place.

Alliant published some GD data for 9mm in the 2004 Reloader's Guide. Check the reference section of the site for the pdf.

Here's a page from an older Alliant manual.

Ha ha, I really like Green Dot powder and find it almost as universal as unique in some ways because you can use green. For just about any pistol cartridge out there from 380 & 9mm to 10mm & 44 Mag as well as intermediate rifle cartridges like 22-250, 7.62x39 & 30/30 and I've become a fan of castboolits.com and have found it to be a wealth of knowledge wear green. Is concerned and they even had a nice spreadsheet put together with the majority of loads you can use Green Dot with in comparison to several other powders and it was rather surprising to find out you could get the same basic ballistic performance across the majority of all the cartridges using less Green Dot powder then you have to use with any of the other powders. My go-to reloading manual is the 11th edition Speer Rifle and Pistol reloading manual for several reasons including green Dot is one of the primary load powders as well as the majority of the powders I use for my milsurp cartridges. Since I met Surplus collector for the most part it works for me but I have a small Library of reloading manuals I've collected because you can't have too many manuals and I even have some really cool old ones that I find useful like an early Hornady I just forget which version off the top of my head as well as one from C&H & Pacific reloading. I'm always perusing the local online classifieds when I have time as well as yard sales and flea markets because I never know when I'm going to get lucky and what I may just fine to add to my bench as well as some more cool manuals I just can't live without

Be aware that some of that Green Dot data when pressure tested showed extremely high pressures. There's a discussion about Green Dot over at CastBoolits.

Alliant doesn't have anything online for 9mm using Green Dot in 9mm, but it appears the subject has been discussed by several folks earlier.

Disclaimer: I have no first-hand knowledge regarding the use of Green Dot power in any application.

Observation:

Alliant used to publish 9mm Green Dot recipes, but they don't any longer.
You can still find some Shooters who really like it in 9mm.
Winchester used to publish 9mm WST recipes, but they don't any longer.
You can still find some Shooters who really like it in 9mm.

Both WST and Green Dot are 'shotgun powders', with some current handgun applications.
Would the reasoning* behind Winchester no longer listing WST 9 data be the same as Alliant no longer listing Green Dot 9 ?
