How about " -06" ?
 

:)Now that the " magnum" question has been answered, does everybody know what " -06" means? I had never really thought about it until I read where it came from.

RE: How about " -06" ?
 

1906 they started it. I believe there was caliber a few years before that was obsoleted like 30-02. Or something like that

RE: How about " -06" ?
 

Right. I think is was Springfield 30-03. It had a problem burning out the bores, so they made some changes that became the standard in 1906, hence the 30-06.

Do I get a prize?:D

RE: How about " -06" ?
 

A prize? darm im to late?

i found a few old 30. army /cases by the river looked pretty old. was that the same as a 30./40 craig or?
yep 06 the year...for the 30/06 but not the 25/06 right? ;)

colt 1911 / 30/06 30.cal / m1/ m14 & 30.cal carbine & 762.54&308. etc

but it seems gun terms etc never follow a long term standard of measurement etc ussally.( bore ,gauge,calibur,

not sure but reading my reloader book awhile ago - seems like the 270. win is more a 7 mm , then the 7 mm.[:o]

It 270. win could have been the 27/06 too? or 7mm .win? lol

Another reason why 30-03 became obsolete was the fact that around the same time Mauser came out with what could be considered the first modern cartridge the 8x57 JS which unlike its predecessor, used a spitzer bullet which scared the hell out of the American ordinance people with its performance, who were still using a 19th century design with the round nosed bullet.

Hntngirl,
I' m not sure what your question is so I' ll try to answer both possibilites. ' 06 is just a quick way too say .30-06. The second possibility is where does 06 come from and what does it mean. Got to go back into the development stage of the .30-06. After our little spat in Cuba in 1898, our military decided we needed a new cartridge. Development started in 1901 and the new cartridge was adopted in 1903. The case was pretty much what the .30-06 is today with two exceptions. The cartridge was loaded with the 220 grain roundnose bullet, and the neckwas longer in order to hold the long bullet. At this point of the story, 1905, the German army brought out a new military cartridge. The big change was the bullet. The new bullet was a spitzer shape. Improved ballistics created quite a stir around the world. Our military did a little checking and changed the military cartridge which was offically named .30-03. In 1906 the US military brought out what we know today as the .30-06. The .30 refers to the calibre of the rifle. The 06 indicates the year the cartridge was offically adopted. The cartridge neck was shortened whe the 220 bullet was dropped. the new bullet was a 172 grain spitzer. Which is why the first rifle for the new cartridge was the 1903 Springfield and the cartridge was the 1906 model case. Boy did I get windy. Hope that this answers your questions.[&:]

:DLOL!! BigBob, I think I' ve probably known that since I was about five! Thanks for the other info though!

ANother interesting factoid- the 30-03 and 30-06 were born in an era where horse cavaly was still a big player on the battlefield. These cartridges were spec' ed to be powerful enough to take out a cavalry horse at 500 yards. Soldiers often complained that the ' 03 Springfield rifle had too much recoil, which they did. I shot about 50 rounds prone through mine a few weeks ago to practice for an upcoming match- it beat the hell out of me. [X(]
Part of the reason why the military' s needs evolved to the 5.45x45 round, no recoil, no cavalry horses to worry about, and battles fought at closer ranges.

U.S. Cartridge, Ball, Caliber .30, Model of 1906 ... which used a 150-grain bullet instead of the 220 of the .30/' 03. We changed because the year before the Germans dropped their slow 236-grain round-nosed 7,8X57J mm bullet and replaced it with a 154-grain " spitzgeschoss" (pointed bullet) at 2880 FPS MV. This load of the Germans gave their rifles a much greater " battle-sight danger space" (range of distances within which you can hit a standing man by aiming at his belt buckle) than our Springfield had with the 220 grain bullet of the 1903 load. So we chopped a .25" chunk off the 1903 cartridge neck, and loaded a 150-grain pointed bullet at 2700 FPS to replace the 220 grain, 2300 FPS bullet (which had also been the bullet of the .30 US Army (.30/40 Krag-Jorgenson). So now we were as dangerous as the Germans!!

What was really ruining bores in 1906, and for a long time thereafter, was not powder but chlorate primers, which required water to wash the fouling out of barrels. When smokeless powder came along, people stopped using water to clean rifle barrels, which was necessary with Black Powder! When they did this, their barrels started rusting and were oftern ruied overnight. F. Hoppe and others spent 20 years trying to develop a " nitro-pwder solvent" to stop this, when it wasn' t even the powder that was doing it!! I' m glad he did, because I love the smell of Hoppe' s Formula No. 9!! However, we didn' t figure it out and develop noncorrosive primers until some time in the 1920' s! The Germans had noncorrosive primers for at least 10 years before we did, and the Army didn' t stop using corrosive primers until the early 1950' s, except for .30 Carbine ammo, which always used noncorrosive priming! But the Army did go back to using water for cleaning rifles, and also developed a bore cleaner that was water-based. It worked pretty well, but did not do as complete a job as plain hot water!![&:]
