GTO,
I use a .204 with 40gr. V-Max and just took one out yesterday.
I think RR's comments had to do with "long range" shooting.
As we all know when RR talks long range, well...............................
So, a 40 gr. bullet gets pushed around by the wind pretty good out passed 300 yards.
That's when I prefer to use my .243 with a 75gr V-max.
