View Full Version : Winchester's NEW 223 and 243 super cartridge data??
11-28-2002, 08:22 PM
Has anyone read info about the 2 new cartriges developed by Winchester????
They are the 223 WSSM and 243 WSSM (Winchester Super Short Magnums) with published velocity of 3800 fps.
I am surprised none of the gun magazines have any info yet about the good news. I only briefly saw the good news printed in a 2003 Browning Catalog. The cartridges looked pretty cool to me, Short and very fat.
Paul what grain bullets for each? I have seen nothing, but have a few dollars burning a hole in my pocket.

On the shortmags.org forum, listed above, you have to click on the forum then click on wssm. There are some pictures. BM

I'm sure that Winchester intended them to be under wraps until the 2003 SHOT Show. That's where all new "miracle" products are unveiled each year. Sounds like the news leaked out, though.
If (and that's a big IF) the rounds are fully ready for release, they'll already have been in the hands of few writers, who are pledged to not release any word of them until the official release date. That's called an embargo. No writer will break an embargo because if he does, that'll be the last writing assignment he'll ever get. Same for a magazine. Print something early, and they get black-listed by ALL manufacturers.
So hang in there until it's official. To be realistic, it takes a year for a totally new cartridge to make it to store shelves, just due to supply and demand. Take the 17 HMR for example. That was announced at the 2002 SHOT Show last February, and it is still hard to find guns or ammo in some locales.
But you saw stories about the 17 HMR within a month of the release announcement. How? They'd been shooting the test guns for months. They simply obeyed the embargo until then.

NOt only new cartridges but brand new guns. That 243 looks like a real good long range gun.
HERE IS THE LINK YOU WANT> ; the 223 WSSM Winchester Super Short Magnum and the 243 WSSM Winchester Super Short Magnum.
I DOn't know what niche the 223 will have but that 243 looks like a 6 PCC or custom benchrest round and should do well on the long range groundhogs and coyotes.
I wonder What the big green monster (Remmington) has in mind for its cartridges.

Thanks guys for giving me the strait scoop on the new WSSM cartridges. I have been away from this list for awhile, working and building a small machine shop attached to my garage. Hopefully I will soon be doing my own rechambering jobs.
Now I know what I am going to ask for Christmas next year. A Model 70 in 223 WSSM.

ok will the 243 be the same length as the 223? i was just wondering, its interesting if it is that length that it will not be legal for hunting in alberta in the regulations is says "it is unlawful to hunt with ammunition having a empty cartridge case measuring less then 44 mm (1.75in) in length" and we can't have ammo less then 23 calibre so the 223 is out anyways - only thing it would be used for is shooting coyotes and not the "whopping mule deer" like it says :)wssm (http://www.shortmags.org/shortmags/stash/wssm_caselength.jpg)

My understanding is that reamer dimensions were finalized in the last couple of weeks. Only prototypes of the ammo have been made so far, if I was told correctly. FWIW, Dutch.

I see one big down side to it for guy like me that like to rebarrel an old rifle that don`t shoot like it used to. The problem is that there are no actions out there now that will handle the new rounds without alot of modification. Bummer. :(
Heres a couple of numbers I found in Shooting Times. The OAL of both of the WSSM offerings will be 2.36" They will be offered by both Browning and Winchester. USRAC has devleoped a totally new short action to acoomodate the new cartridges. Shooting Times has two small blurbs, about the new rounds and the the rifles they will be paired with.
best of luck to all

I am interested in the .243 WSSM and might buy a new M70 SS in that cartridge. I hope the barrel length is 22" and not 21" like I read.
I don't see how a "totally new action" will be made. I expect a shorter M70 Classic and that will be fine. If it's only in the carbon steel Featherweight I will not buy it either. I want a SS barrel at least.
I would not buy a push feed M70 so don't mention the Coyote.
