When I first got my 9.3x62 Prvi brass from Graf's made sence since it was considerabily less $ than Norma. I have had nothing but good results with it other than a few of the 200 cases I bought had thicker than normal rims and required some effort to get in and out of the shell holder. They functioned perfectly in the rifle even though I use them only as practice rounds.
Then someone gave me several hundred rounds of Norma 9.3x62 brass that was very dirty, had green crud on it, stains. I stuck it in the polisher for the weekend and it cleaned up beautifully. I reloaded several now about 12 times with Big Game and 286 Prvi's for practice and none have cracked or show any real signs of wear. Obviously good stuff.
