Wow -- going back a few months on this one. I agree. I have heard enough discussions about primer thickness to make me believe they all have the same thickness and or hardness. I have no clue about the geometry of the anvils but I do know that the CCI military primers are pretty lousy in terms of consistency. I believe that the issued primers are more consistent in fact!
