I don't know where you're getting that you can't take a 77gr reliably to 800. Having a longer bullet doesn't guarantee a better BC or more stability either in a semi because you're limited by pressure allowances and a gas system that bleeds pressure as the projectile is traveling down the barrel. I've personally shot 77 SMK out to 905yd reliably in an 18" barrel. Everyone is also always trying to kiss the lands but I've had several firearms including one of my old 308 Semi's that rather than loading to 2.81 OAL it preferred 2.79 and my groups tightened up another 1/4". Also, even in some bolts you'll discover that off the shelf manufacturers like Remington have deep throats where it's near impossible to reach the lands even if you wanted to.
