Win Ni brass has been good for me, 280, 7 Mag, 270 Win, and some Remington in 7 Mag.
I still shoot Ni brass in Speer and Win in 9mm, 40 S&W, and 45 ACP.
A reloader can not be asleep at the switch. Inspect your cases. Over the years, you will find that some lot numbers of brass are subpar, Ni-plated or not.
Magnum's observation on Ni plated brass scratching dies is spot on. I found that the Ni plating on some lot# of brass is thinner than other lot#. So, I rotate the brass in my fingers to feel for "snags" in the plating.
So, why deal with Ni brass? Because you got it cheap, or it is the only thing you can find in the caliber you are shooting.
