Well if you want to be exact, the .308 and 7.62mm rounds are two different things! .308 is the commercial designation and 7.62mm is the military designation and the two rounds are slightly different. Many

Note to self: Do not, I repeat DO NOT disgruntle members of the classiccmp mailing list! They are dangerous gun toting mercenaries! :)

Many people interchange them and think that they're both the same but many rifle manufacturers warn you against using the wrong type in their product. The difference in the two is in the curviture of the bullet where it seats against the lands in the barrel. If you use the wrong type of ammo the incorrect bullet seating can cause excessive barrel pressure and damage or burst the rifle barrel or action. Furthermore, the nominal bullet size for both the .308, 7.62mm and the .30-06 are all .308 inches diameter. BUT the rifle barrel bore diameter is .300 inches, that's why the rifles that these rounds are used in are considered to be .30 caliber and why the .30-06 is ".30". The grooves in the rifle barrel have a slighly larger diameter (.306") than the bore but the groove diameter is still smaller than .308". The bullet has to be squeezed down in size slightly to pass through the barrel. This is called "upsetting". This provides a gas tight seal and a higher bullet velocity and less gas cutting of the barrel material. And no, there's no "A" in ought. I have lots of hobbys too. Too many!
