I switched from CCI to Remington over 25 years ago. I've neverr had a primer related problem since.
I switched because CCI was having some QC issues bck then. I understand that they've had the problems cleared up for years, and they are as good as any of the others now.
If I couldn't get Remington primers for some reason or another, I wouldn't hesitate to use CCI again.
If you think a mighty military force is expensive, wait 'til you see what a weak one costs.
