The numbers can have different meanings. 22-250 is a 22 caliber bullet in a 250 savage case. A 30-06 is a 30 caliber in a case designed in 1906. Or something like that. 25-06, 6.5-06 yada yada. Some are caliber x weight of black powder, like 45-70. The 7mm08 is a 308 necked down to 7mm.

Pretty sure the 38-40 is actually a 40 cal bullet with the original load of 40 gs of black powder. Can be confusing. Like why do they call it a 38 special when it's a .357 bullet?

Yep...goes on and on...remington 260 caliber is really a .264 diameter or 6.5 08
Some cartridges are described with land measurements, some are groove diameters. Some are neither but just because a space was available on the ballistic tables; i.e..225 Winchester, .223 Remington, .270 Winchester, .33 Nosler.
Why do they name cars the way they do? Same concept. It's more marketing than engineering.
