I can certainly agree with the use of a slower powder like 1F. I have always used 2F not because it is better for me than 1F, as I have never used 1F as it is not as readily available to me as 2F. I have tried 3F, and my guns and I just didn't like it all. I too have better luck with less powder than shot as well. I have become so used to drams or dram equiv. as all my old powder flasks and of course modern shot shell boxes, always talk in dram equiv. I just got used to it. Now I have to do the math to convert to grains.
Yesterday, I was patterning a 20ga. fowler for turkey season. In this gun yesterday, it appears as if 68gr. or 2 1/2dr. of 2F BP and 1 1/8 oz. looks to be the load for this gun. You can see here that the use of more shot per volume, than powder seemed to work well for this gun. I was using one over powder card, no cushion and one over shot card.
