I’m wondering if this is the death warrant for the .260 Remington on a commercial level. I’m sure there will still be those involved in long range competition that are already heavily invested in it so that it wont die out completely.
I wondered that myself in that was this the big "Key Mod v. MLok" reveal that would set one to become the commercial favorite? I don't think we'll see much change as there weren't that many commercial places where 260 was offered that 6.5 CM wasn't; however, the reverse is a different story.
What I do think this means is that there will be more 6.5CM commercial semi auto stuff (SCAR, KAC, Larue...maybe even HK). The KAC 22" 6.5 CM from SHOT may have been a clue.
