Its funny I hear everyone complaining about the Nosler 28 Nosler brass, I have one set of 100 that I have 6 loadings on, That included load development, ladder etc. and some very hot loads during that time. My load is pushing 195's at 3150FPS and the brass is still holding up fine. If people would just season their brass,(shoot the first 1 or 2 loadings on the lighter side ) it will haden the head and you are fine. I do it with all my brass even Lapua I shoot in my F-Class rigs. I have 20 pieces of this brass with 10 loadings on them and still in good shape.
I have seen some Nosler brass that was way soft but I haven't had a problem with the 28 brass or even my Nosler 6mm Dasher brass. I have some of the dasher brass that I have 28 loadings on, and a hot load with the 110 SMK's at that.
