I am looking for load data for Winchester Super-Target AA WST3 powder for either a S&W 40 or 9mm loads.

I have a chance to buy a 3# canister from a fellow who says it can be used for these loads but have not found a formula for either yet.

Go to the Hogdon website. They are the distributors of Winchester branded powders.
 
There isn't much published data for that powder. You can find some info in Hornady Manual #4 and the Winchester #14 load booklet and maybe Hodgdon.com will still list some.
In 9mm 115 & 124 plated bullets, I have had good results with between 4.3 and 4.6gr of WST. With 40cal the only load I have tried is 4.7gr with a 165 plated bullet.

BTW, I think the #3 indicates 3lb size, as the powder is usually just referred to as WST for Winchester Super Target
 
My favorite practice load for 9mm is 3.6 grains of WST and bayou 147 fp.
WST is used by lot of competition shooters and is very popular despite the lack of published loading data. On older Hornady manual has data listed for the 115 and 124. If you want detailed specifics please send me a pm. IMHO WST is the perfect low recoil powder for heavy bullet lead loads in the 9mm
 
When all else fails

Powder Burn Rate Chart, Fast to Slower

11. Alliant Green Dot
12. Hodgdon International
13. IMR PB
14. Vihtavuori N320
15. Winchester WST
16. Accurate Arms No. 2
17. IMR SR 7625
18. Hodgdon HP-38
19. Winchester 231​


Check the chart for Powder Burn Rate (Google is your friend). Data for Green Dot or Accurate Arms #2 will be close and safe. Use a charge weight 1/3 up from minimum and no more than mid-range between min and max charges. If charge weight is between 3.7 and 5.8 grains, a starting load between 4.3 and 4.6 will be safe.​

Yes, I know that this isn't published data, but I've used this technique for 30 years on handgun loads without any serious events with all major manufacturers powder. You need load data for the bullets on hand with the powder you can buy. One incident was 1 pierced primer out of 12 rounds. recoil was mild, ejection was flawless, and accuracy was good. My shooting needed improvement, so I couldn't blame it on the load.​

data

I have an old Winchester data sheet with loads for the forty.

I have sent them to your email as an attachment.

It's good to find any powder that works.

Good luck.
