If you are using one of the 123 grain bullets, (the AMAX, Scenar, or SMK) and muzzle velocity is 2600 FPS or better, than the numbers for .308 work fine. If you are using another bullet, or slower velocities from a shorter barrel, you might want to use a step 4 and multiply x 1.1.
You seek escape from pain. We seek the achievement of happiness. You exist for the sake of avoiding punishment. We exist for the sake of earning rewards. Threats will not make us function; fear is not our incentive. It is not death that we wish to avoid, but life that we wish to live. - John Galt
