Personally, I believe it is basically not enough steel on the bolt when using a fat cartridge like a Grendel. . . .

LR55,
The respective Bolt designs of the CMMG Anvil and upcoming ARAK-21 satisfy the larger Bolt concept for the 6.5mm Grendel cartridge (Case Rim Diameter: 0.447"), compared to the 5.56x45mm cartridge (Case Rim Diameter: 0.378").
