First, let me say thanks for this summary. I do have a question thought about the concept of rim thickness and having more primer compound. In the manufacturing process, the primer and powder and measured as accurately as they can for the machines that are adding these components to the case. Also, the cases have tight dimensional tolerances. They both vary based on the processes used to manufacture and measure/weigh the materials. My question is if the case rim is on the higher side for thickness, that does not mean it will have more primer compound in it, right? These are two independent variables, which are not necessarily correlated like you describe? Could you explain that aspect a bit more, so I understand the relationship with case thickness and amount of primer compound added to the case? Thanks very much..
