    Not sure about the 30 aught 6, however the others were originally wildcats that have been either homologated or just put into widespread use.. The 25-08 is a .308 case necked down to .25 calibre and the .22-250 is a .250 Savage case necked down to .22 calibre...

    Not always a lot of sense in naming conventions for cartridges. Besides the info already given, some, like the 45-70, had a 45 caliber bullet driven by 70 grains of black powder. The 30-30, having a 30 caliber bullet, driven by 30 grains of early smokeless powder. But then there is the 38-40 pistol cartridge which is actually a 40 caliber. and a .38 Special that is really .357 caliber.

    Remember- many names were created by a marketing dept (sitting around with expense account booze, saying "Hey- ya know what would be funny?")

    Yup .30-06 adopted in 1906. Many wildcats based on the good old -06 case including the .25-06 and 8mm-06. The .35 Whelen is also based on the -06 case but they diverged from the norm by paying homage to to Mr. Townsend Whelen.

    There is also the 7mm-08 based on the .308 case, the 6mm-284 based on the .284 Winchester case, etc, etc, ad nauseum.

    30-06 30 caliber created in 1906 it was developed from the 30-03.

    25-08 is a 25 caliber based on the 308 Also called the 25 Souper

    22-250 is a 22 caliber based on the 250-3000 savage round.

    Just like the 30-378 weatherby it is a 378 weatherby case necked down to a 30 cal.

    Now if you talk about pre smokless rounds like the 45-70, 30-40 then it is a different ball game.

    45 is the caliber 70 means it was loaded with 70gr of black powder same with the 45-90 45-110, 50-70, ect....

    Next question young Padawan?

    Well, i would have lost a big bet on this. Although never produced in black powder, I thought it was designed for it. You learn something every day.

    The smokeless powder, the first used for a civilian hunting round, was 30 grains of what is pretty close to today's IMR 4064.

    First one of you that asks me if I loaded the first cartridges myself will get whacked with the aluminum walker.

    The .30-30 was designed as a smokeless powder round. They used blackpower nomencalture because that is what people understood at the time.

    then you get to the propritary cartridges like Lazerroni.

    He bases his names off the groove daimeter.

    Like the 7.21 Tomahawk is a 7mm caliber (.284")

    The 7.82 PATRIOT is a 7.62mm (.308")
