ya it the dents are just like those in the picture.
If the case neck is too dented to allow easy entry of the expander plug, take a pair of needlenose pliers, closed, and push it into the case mouth. A quick turn and the case will be opened up enough to allow for easy entry of the expander plug and you can use your normal sizing die to even up the cases before reloading. No need to throw them away.
toss it..... or install the expander in the die........

Hmmmm lesson for all who don't know, not all FL dies have expanders in them
That appears to be a straight walled case, which of course requires the second (of 3) die to expand the case mouth.
Bottleneck case dies have an expander on the decapping rod.
