Re: OLD CCI BR-2 Primers Versus NEW CCI BR-2 primers
I have both varieties and I have used them for 308's and 30-06. I have not run them side by side over a chrono, but I have not seen a difference as they both shoot the same. No difference in my zero and no pressure problems were noticed.
I bought them mainly for BPCR's, but when my stash of FGMM primers got low, I started using them in my smokeless rifles and haven't looked back. I somehow misplaced 2000 of the baby blue box BR-2's and opened a case of the newer dark blue box one's before my dumbass really looked for the old one's. That is the only reason I have used them both.
That being said, I haven't seen a difference in the loads using them or standard Fed LR's either. I don't know that they are worth the extra $, but we got to get what we can get when we can get it.
