Thanks everyone for your replies. I miswrote or badly communicated my wishes about reloading powders. I am extremely curious. I want to learn WHY a spherical powder is better for this than for that. WHy a slower burn rate for this type is better. Why less of the same powder is better for a heavier bullet in some calibers than in others. Why certain primers react better with certain powders for different applications. I just want to learn more about the intricacies behind the science. There just seems to be a lot of mystery around the science of reloading and smokeless gun powders. I will still follow the data but would just like to better understand it.
