The actual Nosler brand brass pops up fairly often in the for sale forums on this site. Maybe post a "Want to Buy" add. Don't hold your breath on Peterson though.
Alright I'll keep my eye open on here for it, and I know I talked to gentleman from there late last year at show in PA and said it's be soon but have yet to see it
I would rather have ADG brass over Peterson or Nosler and in fact that's the way I went on my 28N as it's stronger and more consistent then the other 2
Just took a look, Midway has Nosler custom, 28 Nosler brass, $101.99 per 25 or $4.08 each. I have 17, 1x fired, Hornady 28 Nosler, I would sell for $30 $25, including shipping USPS priority mail.
