I don't have a misfire problem with CCI. However, my Dillon XL 650 will not reliably seat Federals. The small primers get cocked and crushed about 6 to 10 percent.
I use Winchester primers almost exclusively and they feed like grease through a goose. And no primer failures that I can't trace to high seating or some such operator error.
Oh... the Federals do work better in a friend's tuned PPC revolver. My PPC revolver bangs out the WW's regularly.
