I have used nickle in my 300 win mag, since I bought the gun, my brass have held up very well, and on my 4th and 5th loading, I am starting to see failures in them. I use them cause I like them, and I will continue to use them in that rifle. As fas as 300wsm brass, I don't know where to find it, but if you find 300wsm, chances are they will have 270wsm nickle brass, and I could use 200 of those or so......hint hint. LOL
