I have always used Federal Gold Medal Match or CCI BR2 primers for reloading my 308 Win. I have ran across a couple thousand CCI #200 large rifle primers and picked them up since it's been so hard finding the BR2's. Is there a big difference? Will my zero at 200 yds. change? I understand there's better quality control and less chance for misfires but is there really a huge change in the two? Thanks in advance for any help or experience you have with the two.
