123: I have read that Mashburn worked on at least two versions;a H&H length case necked down,and a slightly shortened version that was more efficient,and which he called the 7mm Mashburn Super.This is Dobers cartridge,and the same one used by Hagel and Page. It is the cartridge my rifle is chambered for.
Hagel writes that there was a 3rd one, which seems to have been a "short" version,which I guess no one liked either. It was the middle one,the one we are talking of here,that became the "Super".This was the one that is variously refered to as the Mashburn, or Mashburn Super.
