Not sure if there was a premium on CCI BR primers before pandemic, I always bought Feds, but, last year I noticed the BR CCI primers were substantially more money, no idea why the difference. Just looking at a site at the moment where they are 15.99/c and 118.99/m, and regular primers are 89.99/m. That's Cdn dollars, so in the US you can discount that 25% roughly.
Another site has CCI34 @ 8.99/c, 4.50 @ 10.99.c, Fed 150 & GM200M @ 10.99/c, Fed 155 @ 8.99/c, Fed200 @ 9.99/c..
Cabelas is @ 13.99/c for CCI BR's
Another has CCI400 @ 9.49/c, CCI 250 & 350 @ 10.49/c.
So, I'm thinking US price ought to be around the 65-75.00/m mark ballpark. I know Vista had said they wouldn't honour previous order pricing in spring 2021, for orders shipping after April 2021, and right now, stores likely have nothing but orders shipped after that anyway. And since fall of 2020, there have been 3 15% increases on primers. So, if primers were 40.00/c, that's 6.00, plus another 6.00+ and another 7.50+ making it at least 60.00 US for some form of an average price.
