That is likely your problem. I stay away from CCI rifle primers because they are harder than the other brands. I have also experienced misfires with them. Your firing pin spring just doesn't have what is needed for them or headspace is incorrect. You can check the headspace with one that misfires. Put a piece of masking tape on the face of the cartridge. Trim it around the case head. If it chambers, your cartridge neck is short. Headspace is measured from the neck midpoint to cartridge face. Case length is another animal.Cci large rifle. Probably shot 600 thru the brick at this point
