Some, but not all, Nosler brass is made by Norma. Other times, it seems to have been sourced from Federal, Winchester, Hornady IIRC, etc. So, I'd like to know if both their 280 Rem and 280 AI brass come from Norma.
I would venture to bet that seeings how NormaUSA has 280 brass listed, that they also supply Nosler. Norma's brass offerings have grown considerably since they opened a US affiliate. As far as case capacity, that will pretty much be determined by the specs of your chamber.
