WSF powder

[MPH17001]

All they had...suggestions for 10mm?  155, 180, 200 XTP

Hodgdon's 2012 Annual shows the following for WSF

155gr Hornady XTP
6.8 grains @ 1100 fps 23,000 psi
8.4 grains @ 1320 fps 35,600 psi

180 gr Sierra JHC
5.7 grains @   950 fps 25,000 psi
7.1 grains @ 1150 fps 35,600 psi

200gr Horady XTP
5.2 grains @   880 fps 26,200 psi
6.2 grains @ 1020 fps 35,600 psi

These are the listed loads, take care and enjoy! 

If you can post a picture of the WSF powder in a scale pan!  Thanks.

That would be awesome if someone who has WSF would post a closeup pic of the powder.

I thought I already did post a pic of WSF, in a thread where we discussed Underwood's 9mm 124gr +P and +P+ loads. I don't remember the name of the thread though. It looks almost identical to what Underwood is using, but doesn't meet the same velocity. (My lot of WSF doesn't, anyway.)

Yondering, I went back and reviewed the 9mm pull-downs and didn't see any post of the WSF powder from you.  It maybe why I'm still searching for a picture...If you could I would appreciated it!

Will post a pic when i get one  thanks for the load data

[Yondering]

OK, here are a couple pics. First one is WSF in a scale pan:



Here is WSF next to Silhouette and whatever Underwood uses in the 124gr +P and +P+ loads. The three powders are clearly different; WSF is more coarse and angular, and Silhouette is more yellowish and finer flakes.

Also, re. the OP's question - WSF performs similarly to Unique for handgun loads. It is not a magnum pistol powder, don't try to get top velocity from it. It's a good powder when used correctly though, and meters well.

Thanks for the picture Yondering...I have added  them to my powder picture data files.  I was trying to buy some Auto Comp but the crap hit the fan and the supplies dried up for now!   

I'll be getting some Auto Comp when it is available...

Thanks for posting the pics Yondering!

Still a mystery powder. Wonder if Brian Enos could ID?

Is there any chance Longshot is the powder used?  If not, why?

I sure wish I could find recipes for the 185 grain Precision Bullets that I  reload. I always end up extrapolating from midway between 180 grain loads and 190-200 grain loads.

I still think it is Winchester Auto Comp powder in the Underwood 9mm +P+

Just to make sure I'm on the same page, does the powder you found in the post I've quoted below represent the same powder that's in the UW 9mm 124gr +P load that Yondering is referencing?
