With BR rifles, we do stupid stuff, so yes it is basically working up a load for each type of primer used. To be perfectly honest though, I am to the point that I do not think it is worth the effort. With longrange guns I never worry with ES anyway. I only look at vertical dispersion. If my ES is 40 or less and I am getting 1/4 MOA of vertical I go with it.
