Don't even try it. If it has Federal, AMERC, or Fiocchi on the head, toss it or save it for scrap.
One correction, if it has FEDERAL, 30-06 SPRG, don't throw them away, send them to me. ( I mean it, I'll buy your once fired Federa brass)
I know that many don't like them, but my Remington 700 works very well with Federal cases, and I have some that I have reloaded well over 30 times.
