For extended range shooting we are interested only in bullets of the highest ballistic coefficient. For example the 30 caliber 220 grain Sierra has a ballistic coefficient of .655. Compared to the 150 grain Sierra spitzer with a ballistic coefficient of .409 the heavier bullet is the clear choice for long range work. Using the figures in the Sierra manual, firing these bullets out of a 300 Winchester magnum the top load listed will give us a velocity of 3300 fps with the 150 grain spitzer.
