Heads up WST Users

[theblacknight]

I recently switched jugs and noticed a big drop in velocity. I've been using WST behind my 150gr Blue Bullets for a couple years now, so I had a lot of historical data from jug to jug. 3.6-3.8 always got 133-135 PF out of my g17/34's.

After the switch, I was barely making 126PF on my Caldwell chrono and steel poppers at a match where a problem. I turned it up to 11(4.2 grains) and I'm barely making 130 out of my 34. It's enough that I'm dropping WST after I run this jug out(no major matches soon).

It's also worth noting that Hodgdon/Winchester does not list WST as a 9mm powder anymore on their website's data page.

Since someone will ask, I'm moving to TitsGroup. :D

I still have about a pound left from a 4 lb jug I found in a backwoods LGS during the great powder drought of 2013. I have switched to BE-86 for all of my handgun reloading, which duplicates service load velocities in the four calibers I use it for. May use the remainder of the WST for reduced power .44 magnum loads. Seven grains with a 240 grain cast bullet yields 850 fps average from a 3" S&W M29.

That TitsGroup powder is Tite :cool:

Stinky, cheap, and awesome.

W231 is sensitive to temperature changes. I’m not sure if WST is but it would be something to consider.

I went back to Bullseye and I’m really happy with it. It meters really consistently and burns cleaner than 231 for me. Seems consistent at any temperature. I always remembered Bullseye being really smokey and dirty. In hindsight it was probably attributable to lead bullets and not the powder.

Wst is very sensitive to temperature. One time I had keep my ammo in the ice box during two day major match:). I stopped using WST for that reason even though I really like how soft it feels.

[theblacknight]

Yea WST is temp sensitive. That was it's only downside to me.

It's free ionbond for your internals!

W231 is sensitive to temperature changes.

It is not. (It used to be.)

[MGW]

Do you know when it was changed?

[Jim Watson]

Would have thought they would advertise that, what with all the puffery from Hodgdon.

[Hambo]

The only data I've seen on WST indicated that the change in velocity is minimal. Anybody have any links or data on this?

From what I understand, a long long time ago (15 years) That is mostly from talking to some of the old crusty reloading guys...

Interesting. I read some "data" off of Enos if I remember correctly. I thought it was recent but need to go back and find it again. Thanks for the info, Les.

I had a thread on here about working up loads with Win231. I used some in a fridge, some in hot water. They was no discernible difference at chrono.

WST is inverse temperature sensitive. However I never had a problem going minor with it in USPSA matches. It will vary some but unless you are really pushing it in gaming power factor it's not an issue. I think it gets a bad rap from it's predecessor 452AA, which it replaced.

O/P you are fine running WST with lead or coated bullets at mild pressures. I wouldn't try to make 9mm NATO or +P loads with it. I don't use it for standard pressure 9mm loads with jacketed either but lead is fine.

Alex Gutt at the 2008 Wi Sectional: sub-minor with WST. He now uses RedDot.

Ha! I now use e3 which I'm told is a modernized version of Red Dot only it's very clean and not temp sensitive at all. I still keep WST on hand for an "emergency reserve".

I used lots of WST for 9mm but gave up on it because I couldn’t seem to get consistent drops from the measure. I have gone to Sport Pistol and VV N310 with good result using 147 gr bullets.
