M118 brass does not have the "knurl", only M852 brass does. FWIW, I know it has been mentioned to not re-load 852, but so far I've had no issues in my, albeit limitied, experience with 852.
I respectfully disagree. Most of last year, I used 1995 852 brass (with the knurl) in my 600 yd - 1000 yd hand loads. I toss it after 5 total firings without any separations.
