Talked to a local purveyor about it a few months ago.
Purple is gov't contract overun.
To me it looked like steel where the purple had rubbed off.
But that could be residual dye.
But the shop owner couldn't confirm.
I know the White box 556 practice ammo is brass.
Olin has the SS practice ammo contract for .556.

Edit: per HD
They have a contract for BP/DHLS but last I saw it was 9mm

Television and radio are most effective when people question little and think even less.
