I used to shoot 72.5 out of a Remington 700 PSS and it shot at 2935 FPS. Very accurate too. My loads were about 3.600” though due to having a very long throat in that rifle.
I just shot a string thru my chronograph(Caldwell) using old remington 700 ss dm last Wed. I used the 208 grain Hornady match (bc 5.33) with Reloader-22 from 68 gr. to 73 gr. They all had OAL 3.58"....
