Depressions inside the case near the base are insipiant head separations. They are caused by firing brass thats too small for the chamber. Nothing to do with a case like the 270 WSM in particular.

Frequent trimming is primarily caused by excessive working of the brass. Again nothing at all to do with the 270 WSM in particular.

Thus your observations are not relevant.
