What to do with this ammo?

[Englishmn]

I'd be tempted to try a kinetic hammer and see if I could get a few broken down... then possibly sacrifice those primed cases to take some measurements of the brass. I wouldn't consider pulling them all down unless I was convinced that the brass was safe to reload. If it checks out, use it since it's already there. If not, pursue selling the rest then.

I was unable to pull with a kinetic puller.
The bullet is too light even after pressing it in some to break the sealant.
