WST is the only powder available in my country, I used WST for my .45 ACP with 200 grains SWC and 230 LRN, but I want to try this powder in my Sig Sauer P228

So try it. Use 231 data. Work-up from min to max.

Should work just fine for light to medium plus loads. If WST is all that is available, at least it is a good one.

Welcome to THR! Dang, that's rough.

Sorry, required THR disclaimer: As there is no current published load data for WST load for 9mm, the usual warning/disclaimer applies - load at your own risk.

OK, now I hope these threads help - http://www.thehighroad.org/showthread.php?t=549498&highlight=WST+9mm
I use WST in my .45 loads, so I was interested to see if it would perform well in my 9mm loads w/ the Missouri Bullet 125gr Smallball.

The short answer is, it does. Here are data for loads at an OAL of 1.09:

3.8 grains 1002 fps
4.0 grains 1024 fps
4.2 grains 1043 fps
4.4 grains 1076 fps

These out of a Springfield Armory XD-9 4" service pistol. I'm running the 4.4 grain load as my production load w/ the Missouri Bullet Smallball.

I've also run the Hornady XTP 124gr jhp with WST; a good load is 4.7 grains which produces about 1140fps w/ an OAL of 1.100, with excellent accuracy. That is in fact my production load w/ the XTP bullet.

Finally, I've also run the Precision Black Bullet w/ WST; 4.7 grains of WST at 1.120. It also does very well.

As usual, work up your loads. I was put onto WST by another longtime reloader who gave me some start loads that worked well, then I worked up to the loads above as the best performing of various amounts and OALs.

I have never seen any factory published data for WST in 9mm. I believe WST is slightly fster burning than W-231 more on the order of Bullseye.

Back when Winchester published their own data it was in there.

I have many of the Winchester data publications both as paper publication and PDF from 1976 to 2002. No 9mm or .38 super data is listed for WST in any of these, of course it didn't exist in '75. Data is conspicuously missing for the 9mm and .38 super. There is 9mm and .38 super data for WSF but not WST. WST data is listed for the .40 S&W, 10mm, .38 spl, and .45 ACP all larger volume cases than the 9mm and .38 super.

If I was to hazard a guess it would be that WST isn't an appropriate powder with small volume high pressure cases. Likely you could get extreme pressure spikes esp with reduced volume or compressed loads that the other powders don't produce. I'd be very careful if trying to use WST in the 9mm, after all if it was a safe combination the manufacturer and other hand load data sources would have provided loading data as it would be in their interest to do so.

Thanks for the information. I've read about some pro-shooters that have used WST on their 9mm loads, but still I'm aware of the small volume of the 9mm's case which can cause dangerous pressure spikes, all though for 9mm faster burning powders are often use and the pressure curves are different.
I'll keep on my research, I appreciate your recommendations.

Thank you very much for the research. I'll begin my tests as soon as I receive 124-125 gr bullets.
