I remember reading about the .223 WSSM in an article some years back. They checked the barrel after just 400 rounds with a bore scope, and found that it had severe barrel erosion in the throat area. And after 600 rounds accuracy had begun to noticeably deteriorate. There are varmint hunters that shoot more than that in a weekend.
Why anyone would choose a .223 WSSM over a standard .223 / 5.56 MM NATO is beyond me. Most all of these are nothing but gimmick cartridges. Even the standard Winchester Short Magnums are not that popular. You can tell because most every time you come across a factory new rifle where the price appears too good to be true, it's because they're usually chambered in one of those dogs with fleas. Brass for the most part is unobtainable, even at places like Cabela's. I doubt when the patent expires that will change much, if at all.
Yes. Feeding issues aside it would have been smarter to load for off caliber rounds rather than the .223/.243 calibers. They didn't offer enough difference from the standard .223/.253 to make enough people switch over to them.
Or, had they introduced them into a semi auto AR type platform that could have taken advantage of the shorter OAL then maybe they stood a chance but the names really didn't define them as something that gave a reason not to buy the established caliber.
