It says "Nosler 280 Ack Imp"...
Its very good brass in my experience...I'm using it for 2 different 270 Winchesters and my 280 Ackley...some folks say it is soft...that hasn't been the deal with mine....when I find max load in a rifle I'm not bashful about it...and the Nosler brass I have is as tough as woodpecker lips.
