Did you get any specifics on the throating operation? Were they different/varied or just undersized? Mine shot the HSM Bear Loads extremely well so I considered not doing it but all the internet wise guys said it never hurts, only improves the results if the throats are consistent. All were undersized with 5 being very consistent with the 6th being more undersized in comparison. I used the 4DReamer kit and made them all .452. I have not shot it yet so anxious to see impacts.
