Hello, I am reloading for a 300 Win Mag. I was using a standard RCBS Full Length, Neck, and seating die. I have only been neck sizing and now things are getting tight. I recently purchased a Lee Collet neck die and have a collet body die on the way. From what I gather, when using the "Inovative Tech. Die" this is only for the bulge in front of the belt. I think that I will also need a FL die but dont know which one to get. Any suggestions??
