Rocky's checklist of things to look for is excellent.
I see one more thing that is worth looking at. What are you using to lubricate the INSIDE of the case necks?
Surprisingly often, if you don't adequately lube the inside of the case necks, the expander ball will pull the case neck forward as the press ram is on the downstroke. And pull it forward just enough to cause trouble chambering the case.
Imperial Sizing Die wax is wonderful stuff, but you need something as lubricant inside the case neck, too. Imperial sells some powdered moly for that purpose.
