    The above chart illustrates the common ballistics of any .30 cal rifle using the exact same bullet weight and velocity. Giving that the rifles fired from are the same brand and barrel leingth.[FONT=Arial, sans-serif]

    Example .308 taken right from Hornady reloading manual; A .168 gr. HPBT loaded with 44.3 grs. of RL-15 powder achieves about 2600fps.[FONT=Arial, sans-serif]

    [/FONT]
    Example .30-06 taken right from the Hornady reloading manual; A 168 gr HPBT loaded with 46.8 grs. of RL-15 achieves about 2600fps.[FONT=Arial, sans-serif]

    [/FONT]
    Where the difference exists is that you can load the .30-06 up a tad bit more with this powder to achieve the full 2700fps. The case is longer and allows for a little bit more powder to be used. Along with the ability of the .30-06 to effectively use .220 gr bullets where the .308 reloading data stops at .190gr.[FONT=Arial, sans-serif]

    [/FONT]
    Powders come in Flaked, Balled, and Tubular shapes, and with the Tubular powder one can more efficiently and effectively use this powder in the .30-06 to achieve the same ballistics listed above. Because the tubular powder takes more room in the case, and the .308 does not have quite as much room in the case as the .30-06.[FONT=Arial, sans-serif]

    [/FONT]
    So the advantage of .30-06 over the .308 is that one can load a few differing types of powder, and you can use more powder to achieve a slight higher velocity. But giving the same weights they both perform exactly the same under the same conditions and rifles.

    I agree that the 06 has advantages over the 308. I think it's not as tacti-cool right now because of its age. If you released a 30-06 rifle today and called it a 308 Super Mag, people would buy it like hot cakes! I'm having my Rem700 gone over right now and upgraded to a precision rifle. I had the choice of converting it to a different caliber and I left it a 30-06.

    The 30-06 is one of the most versatile rounds on the market. You can get loads for varmint up to dangerous game.
