    The 30.06 was developed from the 8mm Mauser and this also produced the Springfield.
    The Spanish–American War of 1898 the us found out the hard way that the 30.40 Kraig had its faults.
    The Spanish had Mausers.

    The case was longer because ........
    Comprehensive tests were conducted in 1904, '05 and '06 which brought about our adoption of the M1906 bullet. This very closely resembled the Germanicon bullet of 1904, being 150 grains in weight, flat-based, pointed and having a cupronickel jacket over a lead core. When this new bullet was first tried in the Model 1903 rifle it posed a very interesting chambering problem. Since the ogive of the pointed bullet placed the full diameter 0.2-inch farther back than the old round-nosed type, the new projectile had a jump of this distance to touch the rifling. This factor permitted gas leakage around the point during this interval and caused erratic positioning in the bore, with the result that accuracy was poor. Correcting the difficulty by seating the bullet farther out in the case left a seating depth of only a sixteenth of an inch - far too little for field service. This also made the cartridge length exceed the permissible limits for use in the magazine. The solution to this problem was attained by cutting 0.2 inch off the rear end of the barrel and rechambering it with a reamer having a shorter leade. This in effect moved the rifling leade to the rear so that a bullet with adequate seating depth was properly aligned with the bore in close proximity to the rifling. With the increased seating depth, the long neck of the 1903 case overhung the bullet ogive, so 0.07 inch of the neck was trimmed, resulting in a revised case 2.49 inches in length and having a capacity of 4.35 cc. This combination gave good accuracy, and all 1903 rifles then in service were recalled and altered to the new specifications, although the rifle's designation of "Model 1903" was retained. The official designation of the new ammunition as noted on contemporary box labels was "Ball Cartridge, Model of 1906, For U.S. Magazine Rifle, Model of 1903".

    So basicly it is a 8mm maiser case with a longer neck in 30 cal.
    Trying to keep up with the Germans and it did a goo job.
    Went on to become the 30 M1icon Bal.

    By the way a us court ruled that royalties were to be paid to Paul Mauser as the 30.06 and Springfield 1903 rifle were mauser copies.

    After WWII rifle barrels were hard to get and were very expensive. The 1919A4 machine gun barrels were selling for about $5.00 each . I have one installed on a M70 Winchester action. I had it turned and polished to the contour of the original M70 barrel. Quite accurate for the time. Some of the were "stellite" lined to reduce erosion for the MG's. If you take an unaltered stellite lined barrel and examine it carefully you can often times, upon careful examination, detect a slight line just forward of the chamber. Stellite, plays havoc with chambering reamers. It was necessary to cut off the original tenon and re-cut as the original tenon was too small for the M1903, M70 or the GEWicon 98 action. Then the barrel had to be re-chambered. The barrel finished off at about 23 inches. I believe that the original barrel was large enough in diameter so that it was not necessary to "bush" the M1917 action - though I never used a M1919A4 barrel on a M1917 action.
    A M190A3, M1903, or GEW 98 action, fitted with a M1919A4 MG barrel, a Lyman 48 sight, a Lyman 17A front sight, and a commercial target stock made a fairly good substitute for the M70 Target rifle that was very expensive and practically unobtainable. On the 03A3, riflemen usually replaced the stamped trigger guard and follower, with the forged or machined variety obtainable through the DCM for about $500.
    I believe that the early 30-06 cartridge was loaded with Pyro DG powder which was a bit erosive.

    May have been the case with the original 220gr bullet, but when the 150gr spitzer was adopted as the '06 round, I reckon the capacity was a bit excessive. 48gr is the oldest charge weight I can find, dating to 1908. Oddly, even the 220gr load was backed off a bit before it was superceded, from 2300fps to 2200, in order to improve barrel life. (Info from History of Modern U. S. Military Small Arms Ammunition: Volume 1: 1880-1939)

    I know the loading of 50 gr of IMR 4895 makes the case about full for the 150 gr FMJ.

    The Hogden manual says 51 grains of the 4895's and Varget are a max load. So does my Lyman manual.
