I have one in an AR platform. Savage has a couple bolt action offerings, I'm sure there are others.
There are a few FB pages focused on the caliber.
Just my opinion - it's interesting, but it's a boutique caliber, despite the military having an interest in it. Remember the 6.8?
Brass is hard to come by, factory ammo is about $26-$30/box. Hornady load data is based on 18" bbl but claims of speed are based on a longer barrel, so there is a little disconnect there.
6mm Arc, 6.8SPC, 224V, 22 Nosler, 6.5 Grendel (AR), they all sit together in my safe and talk about how the 6mm/6.5mm Creedmoor ARs go out more frequently.
Some folks like the 6mm in an AR package, I think the 6mm/6.5mm CMs, or a .243 Win in a large frame AR offer a better option.
Again, just an opinion, your mileage may vary.
