CCI primers are very hard primers. change brands and then try.

In addition to the other primer related advice I'll throw this in. If you seat your primers with the press you can crush them causing primers to fail. Lee and RCBS both make nifty priming tools that allow you to feel when the primers are fully seated and since you're just using hand power you won't crush them.

This may seem like a silly question. But do you get similar problems with factory loads?

That was my second thought after a dirty firing pin channel, which has already been addressed. Are you full length sizing when loading? If you are then I recommend not doing it on cases that have already been fired. Just neck size and see if that helps your problem. Full length sizing would take the brass back to SAAMI dimensions and your chamber may not be within those tolerances. Fire formed brass that is only neck sized for loading is exactly to the dimensions of your chamber and would pretty much counter any minor headspace variations.
