I've been reloading for 50 years and the past 2-3 years Found CCI primers very unreliable. I've loaded then in .380 auto, .357 mag., .40 S&W., .41 mag., & 45 ACP and get 2-4 misfires per 100 rounds in each caliber. Federal primers are the best I've ever used. I would only buy CCI primers if there was nothing else available, and never depend on them for self defense loads.
