Norma makes some if not all of Nosler's brass. Nosler sorts and preps it more but that's it. I'm not a huge fan of Norma but it's what I shoot with in my main hunting rifle. My list in order is Lapua , Winchester that I know will need work and culling but is tough and cheap , Norma which is very consistent but soft pocketed , and then the rest. With Nosler you are just paying double for Norma that rarely needs much work anyway.
