Yes you now can.........................

The first one is the easy one if you can find the brass.
Yesterday I found 100 rounds of 9 m.m. x 23 m.m. 125 gr. Winchester Silvertips Hollow Points,
which by the way Winchester claims to be is the strongest cartridge they ever made.
And they were designed to use small riffle primers to handle 55,000 psi pressure without piercing or blowing out/back.(SAAMI Spec)
(The one problem I have here is I don't own a 9 x 23 gun, so I'll have to pull all the bullets to get the brass.)
They are basically a longer/thicker version of a 9 m.m. x 19 m.m. (Parabellum/Luger) which is actually 19.15 m.m. long.

Just put them in a collet in a lathe and face them to .846 +/- .002 OAL.
You can reduce the powder charge because of the thicker case/smaller volume.

The other is the .38 Super or .38 Super Automatic which is actually a straight walled cartridge (.384 dia.) that is called a semi-rimmed design.
The OAL would also have to be faced to .846 +/- .002 OAL because it is 22.86 m.m.'s long.
The 9 m.m. sizing die will bring the head space end (open end) to around .380.
The rim is .405/.406 diameter which will have to be turned down to a .394 diameter, unless it fits your breech face/extractor and goes into your .356 TSW chamber.
Being a .384 dia. straight walled cartridge it might expand a little at the mid portion of the case to the back end because it's a little sloppy in that portion of the chamber.
Depending on how tight your chamber is, but it's only about .006 total relative to a .356 TSW.
That's about .003 bulge all around in the thinner section of the case, this will taper off to no bulge when you get into the thicker section of the case.

Bumped into Ed Walsh at Cabella's gun counter yesterday.
He is the regional representative for Smith and Wesson.
He admired the .356 TWS but it never seeing production wasn't his call.
He's been with S&W for around 40 years and 14 management changes.
We spoke for about an hour and a half, Roy Jinks, Paul Liebenberg and Jimmy Ray's name came up just to name a few,
Paul and I spoke at length about the .356 TSW when I visited him in Palm Bay, Florida.
Ed was very interested to hear of my positive trials with .356 TSW caliber.

There is allot of info here, I hope I don't bore any of you readers and would like all feedback, positive and/or negative.

It might be a little while before I do the testing of these cartridges for the .356 TSW, I will keep in touch.
If I could find someone that would meet me at the Hartford Gun Club with their 9 x 23 to shoot with then I wouldn't have to pull the Silvertips to get the brass.
Anyone have some spare .38 Super brass for some testing?

Just some thoughts..........

Regards,
BM1

.356 TSW can be rebarreled to .9 mm by Smith for about $2oo.

Yes Sir, they can.
The reason I keep on and on about the .356 TSW cartridge is that it is a tremendous round.
The 9 m.m. pales in comparison, especially if you reload to Peter Pi's CorBon Specifications of 125 gr. @ 1450 fps.

Tom,
Please read my post about converting other 9 m.m. firearms into this caliber,
you'll see my interest in keeping it alive and helping others on this forum that have an interest in this great caliber.

I think Winchester is still manufacturing and selling the Win 9x23 brass.
 
About 10-15 years ago I bought from CDNN several 1000-rd cases of Federal 356 TSW ammo for about 70$/case. They had it by the truckload and could not get rid of it.
 
bad-man-one, how have you been? yes i'm back. send me your address again and i will send you a couple hundred rounds of 38 super to test with.
talk to you soon
Bob
