In regard to your cratering problem, my last 2 factory Rem 700's had the same problem. I just went ahead and had them bushed. A customers rifle I have here, a VSSF II in 22-250 has a visible bevel, why they do this is beyond my comprehension! It craters badly and causes heavier bolt lift.
I will be bushing this also.
Cratering isn't a huge problem if tge cause is known, when the cause isn't known, it becomes an issue.
