Does anyone use WSF powder for a 40

Has anyone used WSF for a 40 with 165 plated bullets

There's data on Hodgdon's site listed as BERB FP. So Hodgdon does.
Spelling and grammar count!

I know about the website. What I wanted to know was if anyone has used WSF in a 40 and what they thought of it.

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 used WSF in S&W 40 pistol loads but went back to Titegroup. It worked ok.

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.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.

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.

Gun: Glock 35

Bullet: Rainier 165 gr. FN
Powder: Winchester WSF 6.3 grs.
Primer: CCI-500
Case: Federal
LOAL: 1.125
Recoil Spring: Factory

Bullet: Extreme Bullets 180 gr. RNFP Plated
Powder: Winchester WSF 5.9 grs
Primer: Federal 100
Case: Blazer
LOAL: 1.130
Average Velocity: 1007.90 fps
ES: 29.02
SD: 9.38
Recoil Spring: Factory

Gun: STI Edge

Bullet: Rainier 165 gr. FN Plated
Powder: Winchester WSF 6.3 grs
Primer: Winchester Small Pistol
Case: Winchester
LOAL: 1.180
Avg. Vel.: 1031.24 fps
ES: 79.04
SD: 32.77
PF: 170
Recoil Spring: Dawson tool-less guide rod, 14 lb. Recoil Spring and Buffer Pad.

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.
