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...

.30-06 The thirty caliber round adopted by the U.S. Army in 1906.

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.
