    Now that hunting season is over it's time to get back to loading for and shooting pistols.
    I want to find a good soft shooting 40 S&W load with 180gr JHP/ TCFP. I was going to start out with WST, but the load data is all over the placed. Max loads range from 4.3gr up to 5.7gr. Hodgdon's web data lists a Max charge of 4.3gr, while an older Hodgdon manual lists 5.0gr. Sierra lists 5.7gr as max.

    So, I came to the experts for advice. WST in the 40, anyone use/try it, where to start and where to stop?

    Thanks

    Interested in much the same,although Im at the point from what I can find for data that Im thinking WSF would be a better choice at least with the 180 gr. SJ 40

    3.8grs. WST w/180gr. bullet of your choice. Soft, very accurate/clean burning, and shoots to POA with the issue sights of most pistols. A great practice and gamer load.

    Athough you can load hotter with WST it has too quick of a burn rate for good results. Pressures run high and accuracy goes to hell. Switch to WSF if you want SD-type rounds. It's excellent for that purpose.

    I am not a huge fan of WST in the 40, but midrange/minor loads w/ 170-180gr bullets can work well. Like tj, 4gr under a 180gr something lead will run most 40s & soft shooting, about 825fps. My working load; 175grLRNFP o/ 4.5gr for 875fps. I actually get better accuracy w/ lead bulelts & WSF though, in the same vel range.

    WST is my fast powder of choice for the .40. I've burnt 8-10 pounds of it so far. Good stuff maynard!

    I used WST for a long time when I used to shoot D&J lead 220s. It worked great and meters like water.

    No idea of where to start with the 180s though.

    SOrry, WST. Pretty soft shooting & almost makes major. You can actually just make major w/ it but I find accuracy drops off. Why I settled on WSF for full power 40s.

    Thanks Fred,
    What recipe do you use for the 175gnlrnfp and WSF? I am buying the Lee 6 cavity to cast for that weight.

    5.5gr under a 170-175gr LFP runs nicely, around 950fps.

    A common load I use is a 155 LRN over 4.0 WST. I don't have these records in front of me, but I think they chrono around 145 PF. Very reliable, nice to shoot.

    With 180 grain jacketed/plated bullets in a stock Glock 35 I got:

    3.4 grains - Malfunctions with weak grip - Chrono'd at 725 fps/130 PF
    3.6 grains - Once in a blue moon malfunctions - Chrono'd at 750 fps/135 PF
    3.8 grains - No malfunctions - Chrono'd at 813 fps/146 pf

    I could probably go to a lighter recoil spring and get the 3.6 loads to run. Haven't tried it yet.
