Even CCI primers are harder than Federals.
With a light striker spring, CCI won't detonate reliably, I had close to a 7% failure rate in my reloads with CCI primers and my USPSA gun with Ghost Rocket setup.
Using Federals, I've yet to have a light primer striker issue, and I've shot 30,000+ rounds with that setup.
