CiP uses millimeters. 6.78mm is .2669 inch.
That is the minimum allowed dimension. Hence, this rifle could never have a .264" groove diameter. Since the bullets used in this cartridge are .264" it totally destroys Bob's assertion that such bullets shot through a barrel with a .268" groove diameter will be chronically innaccurate and incapable of dong the job that they allegedly did in Dallas.
