    Here is amax data

    MV = 2800 Bc = 0.475

    500 yds = 1933 fps

    600 yds = 1785 fps

    700 yds = 1648 fps

    800 = 1521 fps

    Hope this helps

    Thanx Kiwi,the BC of the TSX should be about identical,it holds TV better than I thought it would at that range,should be adaquate for thin skinned lopes.gun)
