Why is Remington developing another 6.5mm cartridge for the ACR?

    Back in July, when the specification for the original Remington ACR specifications where announced, I said one of the cartridges it would chamber was the 6.5mm Grendel. Remington said “6.5mm”, and in the context I assumed it was the Grendel.

    Not long after posting it, I was emailed by a well placed industry insider who told me that he very much doubted Remington would ever produce a gun chambering the Grendel. His reason? The management behind the development of the cartridge left a lot of bad blood in their wake. He suspected that the listing of “6.5mm” was a marketing ploy.

    His prediction that Remington would not offer it has come to fruition. Adam Heggenstaller reported (emphasis mine) …

    Ongoing development will focus on the 6.8 mm Rem. SPC, 7.62×39 mm, a yet-to-be-disclosed 6.5 mm round and, get this, the .30 Rem. AR.

    Will we ever see this cartridge? I don’t know. At least we know why Remington are not just saying “Grendel”.

    UPDATE: My original source just emailed me to suggest that the .30 Remington AR necked down would make a lot of sense! He has a good point. (This is just speculation – not inside knowledge).
