FWIW, I had my ass handed to me by a WM (Woman Marine) shooting her personal AR and a box of storebought 69's. She showed me what she was shooting and asked me if I thought they'd do okay at 600. I didn't have the heart to tell her she should be shooting 80's. I had to hide my score card after she came off the line and showed me hers. 198 and a bunch...and our 600 yard line is not easy. Turns out she had just beaten Watson at Perry for the Womans Service Rifle title earlier that month. Ringer! She was probably just toying with me.
