reloader550 Posted July 25, 2016 Share Posted July 25, 2016 Friend of mine gave me some Winchester WST powder to try, I load 9mm with berrys 115grain RN and Xtreme 124 grain RN with Unique powder. I don't have any load data for the WST powder, is this powder a viable option for 9mm or should I pass? Link to comment Share on other sites More sharing options...
rdinga Posted July 25, 2016 Share Posted July 25, 2016 WST is a great powder for 9mm. I really like it with 147's. Also had good luck using the Bayou 124FP. Link to comment Share on other sites More sharing options...

G T Posted July 26, 2016 Share Posted July 26, 2016 I used it for 9, 40 and 45. Tried Titegroup for 9 but prefer wst. Sent from my SAMSUNG-SM-G935A using Tapatalk Link to comment Share on other sites More sharing options...
EngineerEli Posted July 26, 2016 Share Posted July 26, 2016 I am using WST for 9 minor and 40 major. In 9 minor, I am having a bit of trouble with ES and SD, but I just have to give a little more cushion in my PF. Still feels way better than any other load I have tried to date. I'm using 124 coated lead bullets btw. Link to comment Share on other sites More sharing options...
chuck s Posted July 27, 2016 Share Posted July 27, 2016 Great 9mm minor powder. The biggest downside is that it is very inverse temperature sensitive Link to comment Share on other sites More sharing options...
SCTaylor Posted July 27, 2016 Share Posted July 27, 2016 Great 9mm minor powder. The biggest downside is that it is very inverse temperature sensitive Can you define very? Are we talking 100fps swings? Is this personal experience? Reason I ask is I have heard it ranges ~20fps from 40* to 95* all the way to 60fps in the same temperatures. I'm okay with 20, can load around that. Link to comment Share on other sites More sharing options...
jcc7x7 Posted July 27, 2016 Share Posted July 27, 2016 (edited) I load to 132 minor and 172 major with wst. Never gone below 129 or 169 9 and 40 Edited July 27, 2016 by jcc7x7 Link to comment Share on other sites More sharing options...
MemphisMechanic Posted July 27, 2016 Share Posted July 27, 2016 I like inverse temperature sensitive powder personally. I'd rather deal with that than ones that slow down when it gets cold outside. It's well over 90 degrees for pretty much the entire shooting season in TN. So it's easy to chrono WST at 100* and know that your loads will only get hotter when the temps drop. So you'll always make PF. Link to comment Share on other sites More sharing options...
Alan550 Posted July 27, 2016 Share Posted July 27, 2016 Don't know the exact velocity differences, but I worked up a load @ 40-50* for NRA Action Pistol, which is minor PF. It ran fine until a hot spring day when I left the ammo in MTM ammo boxes on a black tailgate in the sun for about an hour. Turned the 1911 into a single-shot. Wouldn't even extract, let alone eject or reset the hammer/trigger. Link to comment Share on other sites More sharing options...
zombywoof Posted July 27, 2016 Share Posted July 27, 2016 WST and coated lead in my 9mm is great, all weights Link to comment Share on other sites More sharing options...
Out of Ammo Posted July 27, 2016 Share Posted July 27, 2016 I've been using WST for the past 3+ years shooting 125gr BBI bullets. The powder works great. Link to comment Share on other sites More sharing options...
chuck s Posted July 28, 2016 Share Posted July 28, 2016 I load to around 132 PF generally, 3.3 grains of WST using a 147 xtreme. I have to up it to 3.4-5 in the summer . I have seen 20fps swings, but no more than that. No big deal and now I just stay with 3.4 gr and have been safe. Link to comment Share on other sites More sharing options...
