The dimentions are very similar to the 300 Whisper. The only difference is in throat length and maybe the angles of the shoulder. These function in the AR platform with the same BOLT, and the same magazines as the .223. The case is a .223, cut down and re-sized for the .308 bullets. Essentially the same idea as the 300 Whisper, but standardized and submitted to SAAMI.
