The rifle would fire, but would not eject the spent cases. They'd just end up getting smashed by the bolt right outside of the chamber. After five failures in a row, I gave up on this ammunition in this rifle. Just for a sanity check, I put 25rds more of the Speer Lawman 147gr TMJ through the rifle. It again functioned 100%. Given the short ejection distance, I think that I'm going to leave well enough alone. Thanks everyone for your help. Perhaps I was just overthinking things.
