Old gun----new problem....Solution on Page 3

Yes Sir,
maybe they are partial as they did eject in entirety.

Just to make sure if you by chance have both a 7.62 X 39 bolt face Grendel and a standard Grendel. Make sure you are using the right bolt.

I think you have done this before but get some headspace guages and check the headspace of the rifle itself. If the rifle has the right headspace, my bet is the gas system is causing a problem.

The fired and sized brass sticking in the chamber means a huge amount of pressure is causing the brass to flow. Most likely the head is expanded tremendously and the sizing die won't take it out.
