My old Remington 788 shoots great with CFE-223.3900 FPS with 52 grain Hornady A-Max bullets,and the most accurate powder it shot.Sadly,it's the only rifle that was as accurate with that stuff as it was with anything else.Half a dozen 308's and 223's that I tried it in didn't shoot as accurate with it as Varget or IMR 4064,but I never had any pressure problems.
