I know Dennis knows this, but it's probably appropriate to add
for other readers that there are even more common rounds, and 
far slower shots, than the .308, in many contexts.  Typical
civilian fare in the US, with typical muzzle velocities in feet
per second, include

    .22 LR        1138
    .223          3140
    .30-30        2200
    .30-06        2700
    .38            815
    .45 ACP        910


Variations in cartridge loading, barrel length, and so on, can
easily lead to differences up to 30% in muzzle velocity.
