As much as I love shiny brass, in your case I would take a bullet and see if it dropped into the case, if yes then they were not sized, if a bullet won't go in with finder pressure then they were resized. I would take one, load a bullet only and make sure it would chamber in the rifle properly. Tumbling them shpuldnt cause a problem, I am sure a few slip by me with a granule of media in the flasholea, no issues so far. Removing live primers on a press is also a non issue simplly press them out and go.on if you wish, I have removed many.
