Thanks for the SAAMI specs. That is what I was looking for. It looks like my brass is a little on the short side by about .005 (2.452" new out of the bag).

If I am understanding your process, you are blowing the shoulders out instead of stretching the case body. Then you use a standard FL sizer on the fired brass, setting the die up for minimal resizing. I am correct?
