Hornady brass is questionable based on the reading and research that I did when I was in the market. The alloy is too soft. That leaves your choices for brass at Lapua, Privi, Nosler, Jamison or Norma. Not heard anything about Privi .338 brass but the others have good reputations in this cartridge. 100 pieces should last you a long time.

I'm still in the market but not in the short term.
