I've heard the cut vs. button rifling thing. I'm not a target shooter, don't count my rounds in the thousands.
I have a Krieger (cut rifling) 6.5-284 with 5-600 rounds down the tube, showing some throat erosion, but still a half MOA shooter.
I have a 26 Nosler with Shilen (button rifling), around 4-500 rounds so far, looking about the same thru the Hawkeye, also a half MOA shooter.
So, I don't really care what the Hawkeye shows, the bottom line is what happens at the range. If one loses its accuracy edge, then the Hawkeye can help determine what's going on, if and when we may need a barrel swap.
