I have 4 lbs of Winchester WST. It works well in my 45 with cast bullets, however there is no load data for 9mm.

Will it work with 124 grn LRN?

Seems like it would, based on the burn charts. It is placed below bullseye, Solo 1000, Red Dot, and TiteGroup.

Not sure where to even start, or if it is feasible.

Thanks

It is pretty fast for 9MM, but there is no reason it would not work for light loads.

You're correct that's going to be a hard load to find. Even my old Winchester Powder pamphlets don't list it. You'll need to call Hodgdon who now distributes Winchester powder and ask for load info.

I am curious now.

I bought some WST to try out some 45ACP loads and Hodgdon website only lists loads for 38 Spl, 40S&W and 45ACP - no data for 9mm.

Why?

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.

mongoose33, as there is no current published load data for WST load for 9mm, the usual warning/disclaimer applies - load at your own risk.

Hey, thanks for the load info ... will have some fun with WST in 45ACP, 40S&W and now 9mm. :D

Still wondering why Winchester won't release load data for 9mm ... :rolleyes:

Was it prone to pressure spikes at 9mm pressures? Maybe they are pushing W231 for 9mm?

Thanks everyone, that was a tremendous help.

Mongoose, you gave me a great starting point.

Unfortunately, on Steve's Reloading pages, it doesn't clarify if these loads are cast, or jacketed.
