First, longer does NOT equal more accurate. In truth, short and stiff is the most accurate. BUT....you do give up muzzle velocity, and at long range, less velocity equals more wind drift. Between 20 and 24 inch barrels you are talking a roughly 60-100 FPS velocity shift, so run some ballistics tables and decide if the trade is worth it to you.
I have a 16, 20 and 28" Grendel, skipping the 24 because there just wasn't a big enough justification over the 20".
At 800, the 20" is at its limits, at least at sea level, as far as I can determine. LRRPF52 shoots way up high at 5-7000 feet, and gets great results out of his 16". Of course he also hits steel at 1500 Yards shooting from the kneeling position with .338, too! YMMMV!

You seek escape from pain. We seek the achievement of happiness. You exist for the sake of avoiding punishment. We exist for the sake of earning rewards. Threats will not make us function; fear is not our incentive. It is not death that we wish to avoid, but life that we wish to live. - John Galt
