Re: Top three things to reduce ES and SD
When doing load development, there will most likely be a low end sweet spot and a high end sweet spot in the pressure curve with large extreme spreads and deviations inbetween. Then once you go beyond the high end spot, the SD and ES will begin to get larger again. Almost all powders will exhibit this trait but some will yeild better accuracy than others while running through the testing.
It all boils down to a huge variety of things that determine how the internal ballistics will turn out, but all you will need to do most times is change one or more of the four components if the accuracy associated with the good deviation nodes is unsatisfactory.
If it's not far, it's boring.
