This is kind of a continuation of another post. I am having a 338/300 made and need to order some dies. I am thinking I will be using Federal brass and want to order a forester FL die with a custom neck diameter. Problem is I can't load brass with a 300 smk without the die to measure the neck thickness. I am thinking I will buy fed brass, run it through a FL die, trim to make sure the edge is flat, then neck turn to take the high spots off, does anyone know what the brass will measure after I do this? Dave Wilson you out there?
