The light magnums do provide more velocity than the standard loads but they seldom reach the published velocities.They also tend to be very finicky and do not shoot accurately in many guns.Just because a given load shoots accurately in one gun does not mean that it will shoot accurately in others.The bottom line is that if you are happy with 30-06 ballistics keep using your rifle.If you really must have more velocity consider the 300wsm or 300win mag.
