Just looked in Vihtavouri's site. They don't list the 9x23. www.lapua.com/vihtavouri/

I did read an article on the 9x23 about 4 or 5 mos ago, but I don't remember the publication. I seem to recall that the gist of it, was that "white box" 9x23 would be coming out, and was a great deal.

I bought 4 boxes of the factory 9x23. I believe the article was in American Handgunner. Best I can tell, you start out at max loads for the 38 Super and watch for pressure signs. I don't really like that idea. They tell me you can push the 125gr at about 1600 fps! Vit. powder IS my favorite but there is limited data on it. It works great in my 45acp, 200gr swc, 4.5 of N310.

Okay, this one took me a while and I'm still not sure I got it right.
Is it the 9x23 aka the 9mm Largo ?? If so, here is the info you are looking for:

http://w3.one.net/~melchar/largo/index.html

OR, is it 9x23 Winchester? then try this:
(from winchester)

Handgun Data-9x23mm Winchester
Charge Weight Velocity Pressure
Bullet Weight & Type Powder in Grains (fps)
125 grains JHP 231 5.3 1180 38,000 psi
125 grains JHP 231 6.3 1300 46,000 psi
125 grains JHP WAP 6.3 1180 34,000 psi
125 grains JHP WAP 8.4 1435 46,000 psi


If it was the 9x23 Winchester you are looking for, the article was in G&A and a summary of it can be found here:
http://www.productreviewnet.com/abstracts/2/2021.htm

If those aren't it, let me know... I'll keep looking.

We have had good luck with the starline 9mm supercomp with a
124gr hornady flatpoint and vita vohri 540 powder a good starting
place is 8 grains of powder and a overall length of 1.245...

Big John; I am apalled to find that you are working with a very high pressure cartridge with a lack of knowledge as to finding reloading information.

NEVER take anyone's word for a load; use manufacturer's data only.

First, be sure of which cartridge you are working . The nomenclature '9x23' is imprecise, as was shown by Rob's post; I doubt very much that you are working with the antique 9mm. Largo. Remember also that the .38 Auto and .38 Super are also 9 x 23mm.

You want data for the 9 x 23mm. Winchester.
The FIRST place to look is the manufacturer. Check out www.winchester.com, and you will find a wealth of information, including a reloading manual downloadable in .pdf format. You can even download the Adobe Reader if you don't have the ability to work with the .pdf format. The reloading manual has four loads for the 9 x 23mm Winchester!!

Second, check with the NRA. Just e-mail them and they will give you what data they have.

Third; telephone or e-mail the other component manufacturers, especially those who publish data for other manufacturers' components, such as Hodgdon; I have done this to get data not included in their latest manual. Lyman is also another good source for these data. Always use the latest data available; most recent data are generated using the piezoelectric method; these data are much more accurate than the old crusher method data. Winchester dramatically changed their recommendations for the 9 x 19mm Parabellum when they tested the cartridge with the piezoelectric method several years ago (they revised loads downward).

For other firearms related questions, shooter's gunlinks is a good site with links to many different sites (including Winchester). Here is the URL:

Good advice all around, Walt...

(BTW- those loads I posted from Winchest came from that very .pdf file you mentioned which is FULL of good info.)

Rob; I knew exactly where your info came from. I intentionally didn't mention that, as I feel everyone should go to the SOURCE themselves.

But, that said, it was nice of you to post it, and I glanced at it superficially, and it seemed to be the same as what I found on the Win site.

Thanks for the kind words. Walt

Thanks Rob and Walt!! That will give me a few places to start. Mine is the 9x23Win. I have talked with Dane Burns of Burns Custom Guns about some loading and found that he has only used Winchester powder. He has used some 9mm Super Comp brass but would only get 1 major and about 4 target loads before the case split! It is about $50 per thousand cheaper.

Big John; I hope I interperted your post correctly; that you intend to buy 9 x 23mm Winchester cases, and not some other type.

Remember that internal capacity is critical, and that thicker brass means decreased internal capacity. Using the correct brass for the caliber is important.

Further, I suggest you use the recommended primer, which I believe to be the WSPM; the Winchester Small Pistol Magnum. I have found in the past significant differences in the hardness of WSPM primers and small pistol magnum primers of a different make. Since Winchester developed the load with Winchester components, use them!!

Happy Shooting, Walt Welch NRA Life Member
