Thanks for the website. I have not waded through it all yet, But somewhere I recall reading that "X" of BP and 1 1/8oz of shot driven to a speed of 1200fps was 3 dr. I can't remember where I read it, and I was wondering from that thought, if it was 2F. So in a sense if it was 2F and you were to use 3F and only an actual amount of 3F was 2 3/4 dr. that would then be a 3 dr. equiv. of powder. Right? If 2F was the standard of granulation used.
