Ok, I have just bought my third Cooper, a custom classic in 22 BR. According to Cooper, its chamber is cut for a case length of 1.515†and a neck diameter of .255â€. I have 100 rounds of 6mm BR Remington brass on order.
I have also decided to use the Redding three piece die set. I will start with the seating die first, then follow-up with the FL die as outlined in the 22 BR information page.
Now my question, I did not realize that the brass I ordered was primed.
Can I form my brass primed or do I need to remove the primers? Can I safety remove a live primer with my sizing die or do I need to discharge them first? If I need to discharge them, can I use my .308 or will a hammer and punch do the job? If I can remove the live primers, can I reuse them?
Thanks in advance for any feedback.
