Winchester WST powder

[NickSS]

I just picked up some WST powder in a good deal and have been looking for loading data for hand guns. So far the only data I have found has been for 38 spl and 45 ACP on the hoddgon web sight. I would also like to use this stuff of 357 mag, 44 Mag, 45 colt and 9mm if possible. Does anyone have data for these calibers.:-D

wst replaced hp38. Its not the same powder but ive used hp38 data for it without problems. i would think that the hogdons website would have data specificaly for wst.

WST is much closer to Tightgroup for burn rate. WST is my most used powder for 38spl and 45acp. Unfortunately Winchester never gave data for 9mm or 40. I have tried it in the 9 and I have worked up to major power factor for USPSA in the 40. You will need to make your own decision if it is worth it.

I just read a very interesting article on reloading in one of the recent magazines. There is often a reason a powder manufacturer does not provide data for a particular cartridge with an individual powder. It may not be suitable. The author of the article mentioned the S&W .40 in particular - cartridge case "blow outs" from the use of a powder not specifically listed on the powder manufacturers web site. The powder people KNEW exactly what the problem was and that particular powder is flat not suitable, IN THAT CARTRIDGE.

"Logic" does not always apply.

Now, the thing to do, if you want to use a particular powder in a particular cartridge with no data, is to CALL THE MANUFACTURER AND ASK. A phone call costs nothing (relatively, these days) and maybe save yourself some pain. Don't e-mail them CALL them and talk to a real live technician.

I've found nothing in my reloading manuals nor online for the other three calibers listed.

Thanks for the input I will call winchester and hoddgons to see if any data exists.

WST is a nearly-direct substitute for Bullseye. It's a fast-burning target powder.
As such, it's perfect for .45ACP, which was designed around the military version of Bullseye.
It's good for .38 Special for target loads, but trying to get full power will run up pressures quickly.
That's typical of the fast burners like Bullseye, VV310, and the like.
Few reloaders have had success with WST in 9mm and I can't recommend it. For .357, you've got too much air for a too-fast powder.
I see data for .40 S&W, but I'm surprised.
Use it where you'd use Bullseye and it'll do a nice job. It's consistent, clean, and quiet- really.
I can also practically guarantee less felt recoil in your .45 over Unique and Titegroup and powders like that- I tried it in a side-by-side test.

I have used WST in .40 for years. I stick with the starting load, which reliably functions the action.

Look for data here:

Good luck. I think you will like WST.

I really like WST in my 45 ACP loads and agree that it is very similar to Bullseye. That being said, I like to make light loads of 2.4 grains of Bullseye under a 95 grain LRN for 380 ACP. I'd like to find load data using WST for 380 ACP, but can't find any. I'd be interested if anyone has load data for WST in 380 ACP.

+ another on WST being very similar to Bullseye.

I have been using a lot of WST lately. It seems to work as well as Bullseye in the 45ACP/Auto Rim and works much better than Bullseye in my 357s. I noticed the gun doesn't get near as hot with WST in my 357 target loads compared to Bullseye.
