the 30-06 is a morph of the 30-03

in short...the 30-06

The 9.3x62 was created in 1905. The 30-06 in 1906. I think that the inventor of the 9.3 used the Springfield 1903 case (62mm) which was longer than the 1906 case (60mm). There are respected sources that say it was based on the 8mm Mauser case, but I don't know that anyone really knows what case it morphed from. Kudude

ALF,

that's real stretch, suggesting that a 1892 rimmed 2.25" case with a base diameter of .457" somehow turned into a case 2.5" +/- long and .474 diameter and lost the rim in 14 years. I think the Krag taught the military here what they actually needed. Not knocking it, I own both my great-grandfather and his first cousin's Krags, and both will still shoot sub-2moa with my tailored ammunition.

Sorry maybe it's not clearly pointed out, the base cartridge for the 1900 Springfield was not the Krag case but the new round was a rimmed 30-06 of you wish, the Krag had huge influence on the thinking at that time hence the rim and it was only with the 1901 version that we see the rimless version.

Alf is definitely correct on this one. The first of the 1901 cases (which becme the '03 and then the '06 cases) were rimmed, with a long neck similar to the Krag's neck.

Reportedly, the new cartridge was part of a process of designing a new rifle for the U.S. Army. When during the process of rifle design it was decided to require that the new rifle be able to use stripper-clips, it was then eecidedby the design board that the cartridge could NOT be rimmed if it was to function well in the field.



BTW, Alf, if you have it, how about posting a picture of the headstamp of that .45 Roper cartridge you displayed recently in the discussion of the first belted magnum cases....

And, where did you get that picture of the Roper rifle which took that case? (It appears to be exactly the same picture displayed at another web-site as the first repeating single barreled cartridge SHOTGUN, which was made by the Roper rifle Company.) I assume the other site is mistaken, but am curious as to how they may have logically taken something from yet a third site and accidentally mislabeled it....

Previous to it's invention, Roper had some major contracts for single-shot rifles for the Union in the War of Northern Aggression. The rifles they made during the War Between the States are reported some places as having used cartridges made of steel....

Also, if you have any URLs providing data on the Roper belted cartridge rifle, could you please share them? I'd appreciate it as I am trying to add to my library of info on early cartridges.
