Paco Kelly wrote about the 311440 mold and said it was the "Hammer of Thor" out of the 30-30.
As I remember it that may have been the impetus of the GB of that mold here.
I cast a couple of hundred of them and traded someone here for their 150 grain mold of a slightly different design.
I bet I have not shot 10 of them and that may have been out of my tight barreled 7.7X58.
