Winchester WSF

I have always used Tightgroup with 115 grain plated bullets. I've started loading 147 grain bullets and been advised by the owner of a commercial reloading facility (Where I buy my components) that they use Winchester WSF with that bullet. Anyone else using WSF with that, or any other, bullet?

I was about to switch to WSF for 9mm until I decided on standardizing on power pistol.
If I had to pick 3 of the best powders for 9mm, they would be power pistol, HS-6, and WSF.
Used it in .40, and liked it.
There's data at winchester's site

i'm using wsf to shoot the 115 grn jhp's out of the 38 super, not too many reasonably priced powders out there that can safely push one of those up over 1400fps other than wsf

Regardless, I've switched to WST for my 9mm 115gr loads. Very clean and consistent. ;)

(Heck, I've switched to WST for almost all of my handgun loads, save for .44 Special, .357 Magnum, and 7.62x25 Tokarev)

The reason the commercial reloader is using WSF for 147's is probably cost. It takes 4.0 WSF out of my Hi-Power for 990fps with a 147 cast (WWB 147hp's run 1010fps in that gun). It is a decent load accuracy wize and at 4 grains that is 1750 loads to the pound of powder. I use Blue dot for my 147's because in my gun it is a more accurate load YMMV. Nick

Oops, 9mm, thanks.

Tightgroup uses less powder than WSF, he feels it offers less muzzel flip with the heavier 147 grain bullet.

Thanks for all responses.

No disrespect to you or your reloader friend, I'd be very surprised that if loaded to the same velocity in a blind test he could pick out wsf from bullseye and tight group.

It's all in the head, perception is reality.

OK, you load 147 grain bullets (In 9mm.) with bullseye or titegroup, and get as much velocity as a max. load of WSF, HS-6, power pistol, blue dot, etc, without pressure signs, and I'll be a believer.

If you look at published data from Hodgdon,Allaiant and Winchester you can load 147's to the nominal 1000fps with Bullseye, tightgroup and WSF. In fact according to Allaiant data you can load Bullseye faster than wsf! Max loads were never mentioned , only the fact that wsf had less muzzle flip.

But what I'm saying is that you can't duplicate a max load with WSF with titegroup or bullseye, so your comparison isn't going to happen.
Very few of my books even mentions loads for titegroup or bullseye in 147 grain 9mm loads.
Most loads for 147 grain bullets favor slower powders like blue dot.
Just looking at burn rate charts should tell you where the best powders hang out........

You can't compare one companies' data directly to another, too many variables.
That right there is why you have to use several load books to double check your data, because too many companies 'pad' their data to make their stuff look better.

Anyway, use fast burning powder with heavy bullets if you want, but there are better (Safer, and more consistant.) powders for the application.

I'm not going to ruin this thread by arguing in it.
