Am I reading this correctly?

Yea, 223 WSSM is a pretty nice cartridge, so is the 243WSSM. I have both and I'm glad that I reload and have a pretty good supply of brass.

That round looks ridiculous lmao. What is it used for, hunting bears and elephants?

It is .223 Winchester Super Short Magnum.

What is wrong with my ride. Lol

You know, with a big enough hammer that round could fit in a M4. I know what I’m doing this weekend

Yeah, that's .223 WSSM, which would be Winchester Super Short Magnum. .223 WSSM is an entirely different creature from the .223 Rem you're seeking.

ETA: from what I can tell, it looks like .223 WSSM is a .300 WSM case necked down to .223.

Yep, the .223 WSSM missed it's mark because Winchester and Browning decided to chamber this wildcat in a bolt gun with standard ramp angles. With the sharp shoulders of the cartridge, the feeding problems became an issue with shooters. It fell quickly out of favor which is sad. Very few cartridges to this day have the potential this wildcat could produce. Some custom guns were reaching 5000 fps.
It had rounds suitable for hunting from 45 to 87 grain.
Once it faded, the AR builders discovered the feed ramps in the AR platform were perfect, and off they went. The round can run reliably. Modifications to the standard AR platform include having to mill the ejection port more open eliminating the dust cover to accommodate the fat case.
BCG has to be special as well for the big brass.
There are several gun builders out there that can custom make one for a buyer. Twist dependent on the bullet weight.
The round came out in several different calibers. .223 WSSM. .243 WSSM, 25-06 WSSM and maybe one other I don't' remember.
All offered factory ballistics loads about 100 FPS over standard long action rounds. The 25-06 offered zero difference in FPS.
The ability to be used in the AR platform is where that round should have shined, but it faded because of the bolt gun issue. Winchester and Browning do not deal in the AR platform, so they let it die in their line-up.
My favorite round in that caliber is the .243 WSSM. Two uppers in the 1:8 twist for heavies and 1:12 for the 55 grain rocket ships.
Just used the 55 grain to take a doe Sunday. Speed kills. 4150 FPS with a 55 grain Nosler ballistic tip.
I bought hundreds of rounds of brass in 2016, some of which has never been used. The 100 grain in the .920" bull barrel upper run 3400 fps. Winchester makes a brass run every three or four years for that caliber.

Oh ok, I was about to say wtf happened .

Hell I was fixing to sell all but 2k of my 65k stash of 223 & 556 had dollar signs in my eyes for a minute there

 

[OHJEEZE]

Damn, it went down a bit.

Thats a good thing!

Wake me up when it hits $0.30 round

Well, I take that back. I looked up my ammo and it’s around 0.73 a round. $15 a box (20 count). I made a thread selling what I have left if anyone is interested.
