Wikipedia is your friend!I am new to firearms and was wondering about ammunition specifications. What does the .22 stand for or 30-30? What kind of other measurements and numbers should I expect when purchasing various ammunition and what would those be referring to? Thanks
Actually, that is a popular misconception. The term 30-30 was coined by Marlin Arms who didn't want to use their competitor's name on their guns (30-30 = "30 Winchester Center Fire" or "30 WCF"). The -30 stands for the standard load of 30 grains of early smokeless powder, which was on par with IMR/DuPont's 3031..30-30 was never a black powder cartridge but people "Understood" the relative power of 30 grains of black powder.
