For short distances under 100 yards, a heavier bullet of the 165-gr. or larger variety offers more flexibility than a 150-gr. load, which will blowup more easily at high velocites / short range situations.
Distances up to 100 yards typically include plenty of thick cover and the heavy for caliber loads are preferred. Personally, my 30-06 autoloader uses factory 180-gr. Winchester Supreme (Nosler) AccuBonds for everything - previously having used the (nonbonded version) 180-gr. Ballistic Silvertip for longer distances.
