Hello,
I was wondering and read elsewhere about trimming brass 223 and 300 blackout then resizing again, Wondering is it needed? I will be using a dillon cp2000 with dillon trimmer and die and will have an extra stations after the trim die. I have resized and trimmed alot of 223 brass on 650xl not on problem, I am going to be making 300 blackout brass from 223, I have all the dies and trim die for this. is the extra resizing die needed to bring the neck tension back to proper spec? Later i will be processing other rifle brass. Do certain brands of resizing die be better for the final size if needed. Any other info you give me will help.
Thanks for your time
Coleman
