Nine horses, I understand full length sizing as re-forming brass back to original specifications. Since I am firing the brass from the same cooper 204, I am trying to get a bit more of a custom fit by simply bump sizing the fired brass. This way, the brass will be fireformed for that specific chamber. I have attempted to do this by simple backing the full length sizing die out of the press a bit so not as much of the brass will be run through the die in an attempt to preserve some of that custom fireformed shape. Does this make a bit more sense? I do not have a neck sizer, which is why I am going this route.
GLShooter, can you recommend the best way to grid down a shell holder? I am worried that I would grind it a bit unevenly, making lopsided brass.
