I have to say, that some of these reloading issues throw me for a loop, because I don't understand how if you are employing a press, a bullet will not start into the case mouth , after a casing has been resized. I also don't understand how annealing relates to not being able to seat a bullet. As I understand it hardening of the brass would make it lose it's elasticity, therefore when the casing is resized would the case mouth not be too loose rather than too tight. Am I wrong in my understanding of case hardening, or is it that I can't comprehend what is being written. Please help me to understand.
