Sounds like pretty good stuff for a reloader. For widespread use, it's up against some pretty tough competition from 300 BLK.
Honestly, unless you are shooting subsonic suppressed, I can't really see what either round has over the 6.8 SPC, once you have your gun and ammo sorted. 6.8 seems kind of dead in the water these days, though. There are a lot of reasons to go with 300 BLK, most of them about market penetration and availability.
I still haven't found anything I like as much as 6.5 Grendel for a do-it-all light platform, and that's been true for almost 20 years now. I'd take one of the other contenders for a short barrel urban environment, but not by a huge margin, and there's way more open desert than city buildings where I live.
