the 30-30 is also a 7.62x51r just FYI
The first 30 is in reference to the caliber and the second is in reference to the powder weight. The 30.06 is similar-the 30 is the caliber and the 06 is the first year of production.
Before it was called the .30-30 it the .30 Winchester Center Fire made by the Winchester Repeating Arms Company. When Marlin also made a rifle to fire this round it was referred to as the .30-30.
Some cartridge designation refers to the caliber and length, such as the 8mm Mauser which is 7.92 millimeter caliber by 57 millimeter in length.
The British extend their caliber to the third decimal point, for example the old .58 caliber Enfield musket was designated as .577 (caliber) by 60 (grains of black powder) by 525 (Bullet weights in grains) thus: .577/60/525
