I was resizing some brass today and I noticed a few cases that had flat spots in the mouth and some dents along the body of the case. These were in the case before resizing. I lubed these cases well and then ran them through the resizing die (Lee full length resizer). They seemed no harder to resize than any of the others. The question is would you use them? After resizing the case mouths look good. The one with the dent still has a small dent but I can barely feel it. One other thing I noticed was a line near the head of the case. I think this is where the case fits in the shell holder (it looks about the right position for that). On some of the cases I can feel a noticable transition at this line. On others I can't really feel anything here. Is this normal? I'm using a Lee Breech Lock press with a Lee full length sizing die. .30-06 brass both Winchester and Remington.
