Late to the party here but if I understand correctly what you're describing sounds like the rim of the case is catching the square-ended ejector and not allowing it to pop up and square up with the chamber. I had this happen on my first 6mm Grendel. The solution is as simple as beveling or rounding the end of the ejector pin. Won't cost you a penny to try it.
