World of difference between 150+ gr 762 and ~77 gr 556 at distance.
Statistically, the 762 hit percentage, (180gr) with 5% wind uncertainty at 600 yards, on an IPSC target, can be as low as 70%. Contrast this with 300 WM (230gr) same set of assumptions, is 94%.
556 will be even lower. So, it all depends on how well you can read the wind.
How much lower will depend on bullet choice and MV, assuming you've accounted for the other variables.
Not questioning your ability or trying to talk you out of trying. I'd actually like to see video once you're done.
I'd probably go for 20" to squeeze every last drop of MV as possible. I'm not a good enough wind reader to attempt it, but it would be fun to try.
