While Partitions wouldn't be my first choice for shooting much past 500 yards at anything, the 200-grain .30 isn't too bad. Bryan Litz's range-tested data gives it a G1 BC of right around .500 for velocities from 3000 fps down to 2000 fps, very close to the BC Nosler lists. When started at 3000 fps velocity at 500 is still over 2300 in typical Montana hunting conditions, and wind-drift isn't too bad at all--one reason I've used it considerably in the .300 Winchester and .300 Weatherby, where of course it also works great close-up.
Litz's G7 BC is .249 across all velocities from 3000 down to 1500, again not too bad.
