Well i am new to rifles and the ?gauge? so what does 22-250 mean? or even 30.06,and why not 30 instead of 30-30 What does this all mean? or even 7mm 08 this is just so confusing to me when i am so used to a 12ga or 20ga heck the biggest rifle i ever shot was a 22lr. now Pops has a .243 35Rem and a 270 that i am shooting (really like that 35) but i just dont understand the nameing of the Caliber or whatever.


Oh and Pops was wondering what HMR means in the new 17HMR

    HMR= Hornady Rimfire Magnum, and cartrige identification can derrive from alot of different things,the 30-06 comes from the caliber 30 and the year introduced or adopted 06= 1906, or caliber size and the powder load 45-70 is an example 45 caliber with 70 grains of black powder. Really the names can mean almost anything, I just accept it so I don't get alot of headaches...

    Gauge means how many steel (steel? iron? lead?) balls of a certain diameter weight one pound. Ergo, 12 balls that would just pass through a 12 gauge bore equal a pound. 22-250- I'm not sure. It is a .22 caliber, and if I had to guess, I would say it started as a wildcat .250 that was necked down to .22. 30-06 was covered, 30-30 follows the caliber/capacity rule. 7mm 08 also has me stumped, but it sounds like an 8mm necked down to 7mm. Really, some of them make no sense; some have more than one name; some are very misleading, and some are just "fun" names, like the .14 flea.

    22-250 is the .250 savage necked to .22 caliber.

    30-06 is cal.30 1906 it was preceeded by the 30-03 as introduced in the 1903 springfield there was a bullet and case neck change in 1906.

    30-30 .30 caliber 30 grains of smokeless powder. This was one of the first smokeless powder cartridges introduced in 1895 for the model 94 Winchester.It carried on the tradition of naming powder weight after caliber.

    7mm-08 is the .308 winchester necked down to take the smaller 7mm bullet

    Gauge is the number of lead balls of that diameter that can be made from 1 lb of lead. This is why the number gets bigger as the bore gets smaller.

    A really good book that you should get, would help you alot, is Catridges of the World, by Frank C. Barnes.



    If I'm wrong please correct me, I won't be offended.

    And to go one further with the 22-250 thing. Yes it is necked down 250 Sav, which is a necked down .300 Savage, originally called .250-3000 as one of the first cartridges ever to exceed 3000 fps.

    Imagine that, I learned something new today, already. I had never heard about the way guage is determined, always knew what was what, but I had never heard the real deal behind it all, thats both interesting and pretty cool to know. Why the balls thing though, were balls the original projectile used in guns defined by guage?, as opposed to the shot that they use now??

    Lone Wolfe....if you're not confused, you obviously don't understand the situation.

    Frequently, but not always, the second number(s) refer to the number of grains of black powder in the original loading.....so, .30-30 is 30 caliber with 30 grains of black powder, .44-40 is 44 caliber with 40 grains of black powder. However .38-40 is 40 caliber with 38 grains of black powder, .30-06 is 30 caliber, adopted by the U.S. Gov't in 1906, .250-3000 Savage is 25 caliber with a muzzle velocity of 3000 feet per second, etc., etc., etc.

    .38 Special is actually .357 (36 caliber) while .38-40 is actually .401 (40 caliber) and .303 British is actually .312 (31 caliber), and on, and on, and on.

    Now, if you understand all this, will you please explain it to me?

    Xracer, The 30/30 wcf and 30/40 krag were the first smokeless powder rounds in this country. Neither was ever factory loaded with black powder. Being the first they just carried on the previous system.

    I second the recommendation of getting "Cartidges of the World". It is an excellent book. You can't go wrong with it.

    ...don't forget that caliber measurements are generally taken from "land-to-land".....but sometimes from "groove-to-groove"...(now everyone should be throughly confused)
