The traditional, flat base design of the Pro-Hunter has been skillfully blended with Sierra’s world-famous accuracy. The custom-tapered Pro-Hunter jacket design helps assure maximum expansion, optimum weight retention and deep penetration for game-stopping, 1-shot performance. The 30 Caliber 150 Grain Round Nose Pro-Hunter is an excellent choice when good expansion and deep penetration are required at short to medium ranges. This bullet works great for whitetail or black bear. This is not loaded ammunition.
