I know it isn't a factory Ruger.
Clay and I talked about that limited run as well. I told him that I wouldn't be getting one because of the .314 diameter barrel.
It was actually JB that told me it was a .314. He had one for a while. I suppose I could have made some .314/.315 cast bullets, but that made my mind up about making a 30-303 instead.
What diameter did you go with for your No 3 barrel?
