yes its a 30-06 with the shoulder changed to 35 degrees and the body taper removed just like the 6.5/06 AI except the shoulder is pushed forward far enough to allow only one caliber of neck length, rays reamer is based on the 270 case length so it'll have a longer neck.
I'm not sure if Rocky Gibbs built 7 or 8 calibers on this case I know there is the 240,257, 6.5, 270, 30 and 35, not sure what the rest were.
