Was helping out a friend that has an indoor range. Running a magnet across a pile of cases and apparent brass cases clung to the magnet. They all had the Xtreme headstamp. I've reloaded some of these in the past, but am rethinking because they are brass plated steel. These cases are usually sold already sized and primed. Anyone with experience?

I ran into some of this brass again and find that only the primer is steel. The case is brass only. I should have checked that before my previous post.

Thanks for the update. I'm about to receive 800 of their brass from the Cabela's/Xtreme rebate (buy 500 Xtreme bullets, get 100 free new unprimed brass). So good to hear they are indeed all brass.
