I have wanted to build a 5.6x50 Mag. for several years. The dies are available and so are reamers. The holdup is finding any brass that is available at a reasonable cost. Huntinton's used to have brass available but for 400 rds of brass was about the same cost as a new Remington action. Does anyone know of a source for German or Austrian brass, either new or once fired? Seems like there should be a distributer somewhere over there that could ship the brass as a reasonable price.
