Another consideration is that Howa makes a 6.5 Grendel bolt gun. Sadly no mag compatibility with 6.5 Grendel AR mags. I like the idea of a bolt gun and a semi in the same caliber. The bit I've read on the Howa is with the right load it is sub MOA, 22 inch barrel. Build an AR in 6.5 Grendel with a 18" barrel in a lighter weight as a hunting rifle.
