This is really nice brass, measures out to work well in a 6XC II chamber. I'm using it in a 6XC with .275 neck, so far seems to work as well as the Norma. Love the ammo box when you purchase it 100 round pieces, this is the way high quality brass should be packaged. Alpha brass is great brass when you can get it.
