Well I might just have to try the standard primers. Apparently, the Norma brass primer pockets don't play well with the Winchester primers.
I haven’t bought any new brass since the beginning of the Obama years when components were scarce, but I too had problems with Winchester primers “not playing well” in any of the new brass that I bought back then. They sat rather loose in the pockets of the brass of that time. Also had the same problem with Remington and Federal primers, all of which were a tad too small or the primer pockets were a bit too big, what ever the case may be.
The ONLY primers that I found to fit snug in any and all brass were CCI 200 and 250 M. So I have pretty much just stayed with those on every thing now.
