Twist would have far more to with stabilization than barrel length.My only quibble with it is the barrel length at just under 21". Yes, velocity gain is minimal after 18.5", but stabilization of heavier bullets will suffer.

And people are cutting their barrels shorter with a suppressor, regardless of whether they use a heavy bullet or not.Yes, but some people see heavy bullet groups tighten with the addition of a silencer. Even a little more distance of gas propulsion seems to make a difference.
