Re: How tough is Norma Head-Stamped 300 Win Mag Brass?
Norma brass is going to be tough to find. I use RWS and 77 grains of H-1000 with 208's and absolutely no pressure signs and 2900 fps. Can't get any faster than that out of any brass on the market. The brass is thick, and after I uniformed the primer pockets I still have to seat them on the press because of tight primer pockets, going to anneal every third firing and hope to get 7+ firings out of it. I fl resize (barely bumping shoulders back) after annealing and neck size with Lee Collet on the two firings that I don't anneal.
