i am ready to build one on a 700 remington to see how it will feed without a belt, hucking a 180 Berger, and not using an extended Wyatts magazine box which I have done with the 7stw and the 180 berger,,, I didnt want to neck down 375 to 7mm, and deal with inside neck reaming or outside turning,,hoping for a smaller ruger caliber like a 7mm or 30,,, seems the necks would get thick, I neck 376 Steyr down to 8mm, a bullet just touches the inside of the neck on a fired case....
