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 7mm 140 Grain Pro-Hunter is an excellent bullet for medium sized game in all 7mm cartridges. It performs best at distances no further than 450 yards. This is not loaded ammunition.
