Im looking for info as to why the Sierra game king is not a popular long range hunting bullet. I myself like berger and plan to use them, but the price and reputation of sierra is attractive. I more specifically am interested in the 175 grain 7mm Spitzer #1940. At ranges of 700 yards or less in a 7mm rem mag i think this bullet would preform very well. It has a bc of .533 and is of sierra quality.
