I'd add Norma, and rate them as follows:
1. Lapua/Norma (either one)
2. Nosler
3. Hornady/ Rem/Win/Federal
I have read that Federal makes the Nosler brass and holds that brass in a tighter spec range.
I have not heard that. If you just look at what types of brass that Nosler makes it lines up with the same rounds as Norma.... just say'n.
I mean when Norma came out with 17 Remington brass so does Nosler. Norma makes 221Fireball now so does Nosler. Nosler has 6.5Creedmoor so does Norma. I don't think Federal does any of those.
I do know that Federal is my least liked brass that is currently made.
