full length sizing die and factory new cartridge cases

[pocketshaver]

I use RCBS dies and don't bother with Lee. I size my new brass just like fired brass and there's no troubles or issues.

I have no fired case, OR fully sized case to use to get my die set up, the technique I learned with LEE email support was to install the die body into my hand press. attach the shell holder, and adjust so the arm is in the correct position. Then insert a sized empty cartridge, or a fired empty cartridge into the shell holder and drop the resizing mandrel into the empty case and run it up into the die and use that to adjust the mandrel into the die body so the stupid thing doesn't bottom out early on the cartridge case and pop out.
