Mr. Katt- I re-read the Starr "book" again and noted that Mr. Starr always liked 1F powder in his larger bore loads. Also, when I did the measuring and calculating (drams vs. grains is confusing to me) it seems that almost all of his loads closely match the Equal Volume of Powder and Shot theory. So, I will try this old idea soon, as I have previously used 2F powder and it did give pretty noticeable recoil when paired equal volumes with bigger shot charges. The 1F might possibly also give better shot patterns due to lower pressure than 2F; maybe this is why I've had better luck with less volume of powder than shot when using the 2F granulation powder. Lots of fun experimenting to come!
