Anybody see these yet? Not the heavier tmk being talked about, but. . . . @Formidilosus ?
Edit to add: also see a 142gr 6.5mm and 175gr .308 version. . . .no .224
 
There's a thread on them with lots of folks saying "we have the TMK and dont need this bullet," but regardless, this is an interesting new offering with a BC between the TGK and TMK. I'd be intereted to hear accounts of the terminal performance before I test some in my 6.5CM.

I actually found that thread right after I posted this. I was kinda excited to see them, but the consensus so far is kinda "meh".
 
I’ve got both the 107’s and the 142’s. I shoot the regular MatchKings every weekend in PRS matches, and have found them to be amazingly accurate consistent bullets, so I grabbed some of the MK-X’s. Worked up loads in my 6 ARC and my 6.5 Creedmoor hunting rifles. They are also hammers, and super consistent at range. I’ve trued the 6’s to 600 and the 142’s to 800 and was very pleased with them. They are also super consistent. I’ve yet to kill anything with them, but hope to remedy that soon. I’m assuming these will perform like Bergers with a short neck then a devastating wound channel. I’ll update once I put one in an animal.
