223 brass rippling

[270WSMXBolt]

The marks on those two are actual factory crimp marks, not from the FCD.

That's either factory or LFCD marks. Yes. They are not marks from the necks flowing into the rifling as per why I made the comment.

I understand your comment.
However, those marks are not from the Lee FCD. They are from factory ammunition.

Somebody borescope the poor souls chamber for him….

It looks to me like he’s either got one dirty chamber, or a heap of galled up corrosion in the chamber……
