For 7mm Rem Mag, I bought 2x boxes of Nosler Custom Brass and the TIR was >.005 at the shoulder on a large chunk of them even after resizing (which you basically shouldn't have to do with that brass).
So, I complained and they didn't bat an eye and replaced both boxes. ...then, I realized my T-Mag was not helping and got a Forster co-ax press and life is good. ...My bad!
But, kudos to Nosler for customer service.
I later discovered Norma makes 7mm RM brass and I've found it to be the best.
RP and the others go "bang" as well. But, #1 Lapua and #2 Norma seem to form better in the dies, with less runout, more even neck tension, and seemingly longer life. JMHO
I like Fed GM215M for the magnums and CCI BR2 for plain large rifle.
