Does anyone use WSF powder for a 40

Hope I don't get in trouble for recommending another site, but check the Brian Enos forum. IIRC, they are big fans of WSF powder.

I really like WSF too, but there's very little load data available so I just "wing it" (pretend it's Herco and stay well shy of max loads) and it works well -- but that's mostly in revolver cartridges. I don't load .40 at all, but I think it would be better in auto cartridges like .40 and 9mm because it's not bulky like Herco.
 
I have not tried it yet. I am working on loads for 10mm and .40. So far in the 10mm for heavy loads that are accurate Blue Dot works well. AA7 is the next one I am trying as it meters way better from a volumetric powder measure.

In .40 so far my fave is Win 231. It still works. I will be trying Power Pistol at some point in time. If I come into a can of WSF I may give it a try.
 
Watch it with WSF. It's the most reverse temperature sensitive powder I've ever
encountered. Probably not a problem with low/mid loads, but if you are loading
toward the top it might be too "hot" in cold weather.
 
I used WSF quite a bit until I ran out. Here are two loads for 165 plated bullets - one for my STI Edge. I tended to use WSF with 180 gr. bullets in my Glock and never did check the velocity with 165s. I did chronograph the Edge load, but it was seated to a longer length.

I think WSF is one of the best powders out there for the 40 S&W. Good velocity without the pressure problems of faster powders, low muzzle flash for SD loads too.

I've been using this since 2007 as my only 40 loading;

Bullet: Hunter's Supply 180g Lead TCBB
Powder: Winchester WSF 5.6g
Primer: CCI 500
Case: Starline .40
LOAL: 1.125" or 1.130"
FPS: Never have chrono'd this load but would guess around 950-975FPS
Gun: Ruger P91DC w/Stock Recoil and Hammer Springs

Hope this is of some help to you, even if not the 165g bullet load you are looking for, It's all I got.
 
I use it and like it in 40 S&W. Have tried Unique, AA#5, and Power Pistol and prefer Win SF. Have read it produces softer recoil than others and I believe it is very slightly softer. I agree that with 6.0-6.3 It would do well with 165 gr. plated or jacketed.
 
Sorry I didn't answer the main question of the op in my above post, so here it is;

The load I listed above, I shot next to my friends .45 loading of 5g of 231 and 230g lead bullets, and I found a definite difference in recoil as my load shot softer than my friends did (his was out of a comp'd Government Model). I have had absolutely NO issues with pressure spikes (as I have run as much as 5.9g of WSF with the same bullet, but my shot to shot times started to increase so I backed my charge down). No leading (I had lapped my barrel before hand), and no unburned powder left over either. The only place that I found any load info was on Brian Enos's forum (seems that WSF was the powder of choice in IPSC shooting for the .40 once upon a time), but have since bought "Lyman Reloading Handbooks" # 47, 48, and 49 that have loads listed for WSF, though not for your 165g bullet, so you'll just have to figure a good starting point from what there is listed for the other weights and styles of bullets listed.
