Browning has stopped chambering rifles in the 223 WSSM, so there are NO new rifles coming out in this caliber - that is the official death knell of the .223 WSSM.
The caliber had very serious accuracy problems... the 12" twist meant that you limited to the 64gr soft points and the 60 grain plastic tipped bullets - at a time when large case 22 bore shooters are going to 75gr A-Maxs, and 80gr SMKs.
So it was a "gee wizz" caliber that had a horribly short barrel life, even with the chrome lined barrels, and accuracy was typically 2" to 3" at 100yds.
You couldn't get it rebarreled, cuz the standard stainless barrels had less than half of the barrel life of the original barrel (600 rounds??), so by the time you worked up a load, the barrel was close to the end of it's life.
It was a bad idea by the class of folks that are slowly ruining the gun business... people that have an MBA from Harvard business school, but never owned a gun. It's all in the marketing for them.
