Default Cartridge Numbers?

I was asked a question today that I did not have a good answer for. What does the 06 mean when referring to 30-06 or the 8 when referring to the 308? Can someone help out?

"30 cal 1906" which was previously 30-03 (30 cal 1903) which is .308 bore diameter

308 Winchester .308 bore diameter

and then we have 32-20 ......32 cal 20 gr of black powder..... or 47-70..45 cal 70 gr of black powder...or 30-30 which was never intended to use black powder

and the 7 x 57 (as an example of Euro metric designations) 7 mm x 57 mm case length


or howza bout 38 spec 38 cal groove to groove..... 357 mag same diameter but measured land to land

confused yet?


Well so are most people so don't feel bad...

Default well

The 06 is the year of adoption by the USA 1906.The 30 is the caliber so they put the two together 30-06.There was an earlier round they tried 30-03 but settled on the former. The .308 is the bore size .It uses the same diameter bullets as the 30-06,30-30,30-40 Krag and 300 win mag.The 30-06 case length is 63mm and the .308 51mm.Harold

Cartridge naming is an art, with little rhyme or reason. 7.62x 51, also known as .308 Win, has absolutely no physical similarity to the 7.62x 54. Heck, even the bullet diameters differ. throw in marketing tool exaggeration and it becomes a jungle.

And .303 Britsh that uses a .312 bullet

And let's not forget the necked up/down cartridges that keep part of the number from the parent case. Like the 7mm-08 Remington, the .25-06 Remington or the .338 Federal. Oh, wait... forget about the .338 Federal

As in the Remington Ultra Magnum line of cartridges? It is marketing speak to distinguish them from the Remington Magnum line of cartridges. I mean, who would want a "Magnum" when you could have an "Ultra Magnum".

The 7-06 was a flash in the pan and the 7mm Express didn't catch on, but man that 280 Remington is just awesome.

Thanks guys, appreciate the insight you have provided. Appears some have a logical origin and others are a mystery.

I have never heard that !
can you give me some research info on it?
As far as I ever knew it was always loaded with 70 grains, with a 405 and them a 500 grain bullet IIRC.

I think it was the 500 grain load for the rifle and 405 was for the carbine.

Or the 22-250 that is a 250-3000 case necked down to .22 cal. The 250-3000 was a shortened 30-06 case necked down to .25 cal and was able to achieve 3000 fps hence the .250-3000 designation.

I suspect you are correct Cat.

There are lots of guys pushing 45 cal bullets with way more BP than that and the recoil is quite managable.

Trying to make sense of caliber designations is as futile as trying to figure out powder burn rates using "the numbers".

Default 250 savages

One of my favorite caliber stories for the firearms course is the 250 savage, formerly known as the 250-3000. The first 25 cal bullet to break the 3000 fps barrier.
this of course was the predecessor to the now infamous wildcat, the 22-250, which was a 250 cartridge necked down to 22 caliber.

And then there are things like the 450bpe, 450#1, 450#2, 450Rigby, 400Jeffery and 404Jeffrey, 400H&H, 400/360, 450/400NE and 450/400NE-3-1/4, 297/250Rook,295/300 Rook, 300Sherwood.
Have to do a wee bit of reading to sort some of the English cartridges out, many are not what they seem to be, by the name. And then the Europeans had to rename some of them to metric designations.
If you think of a "new" cartridge, and you think it hasn't been done already, you very likely could be wrong, or just a couple of thou out on one of the case length or shoulder or neck measurements.

275 Rigby!!
Only reason it's called this?
Because the 7MM Mauser was already in existence!!
And of course there is the 7/30 Waters, a cartridge named for the famous Ken Waters - who apparently was a bit embarrassed when he found out it was named in honour of him!

Then there is the 307, just a 308 with a rim.

Default 45-70 Black powder loads

Barnes cartridges of the world book it says;

The recoil from the infantry rifle load, the 45-70-500, was murderous in the lighter, shorter, carbine. They ended up with a .45-55-405 for the carbine. The carbine load would easier to shoot from a horse.

A fellow at a CAS gunshow booth told me the foot soldiers would slip a few rifle loads in to the mounted soldiers carbine loads to see if they could knock them off thier horses.

There was also issued was the .45-70 "Forager" round, which contained a thin wooden bullet filled with birdshot, intended for use hunting small game to supplement the soldiers' rations. This round in effect made the .45-70 rifle into a 49 gauge shotgun.

My trapdoor carbine load is 55grs. 2F with one wad and a 405 cast bullet.
