Any info out there on 30-06 shortened to 2.125" COL? The rifle barrel is marked .300 and originally we thought this was a 300 Savage however the Savage is short in the neck and slightly fatter. First I've seen...appears to be a 50's rifle.

Is the 2.125 Cartridge overall length or the case length? If it is the overall length, what is the case length?

Case length is 2.125".

In France there is the 30-06 SHORT which is a 30-06 chamber made shorter. This so that the rifle becomes incapable of chambering regular 30-06 and so no longer a prohibited military calibre weapon.

Does it have shoulders angles like this? This is simply a shorten 30-06 drawing.

Your drawing is a correct representation of the case and cartridge configuration. Does anybody have info on this cartridge? Ron

Have you taken a chamber cast? Have you compared it to a 308?



The 308 was introduced in the 50's, and it might have been an early attempt at a chambering.

And as mentioned in the gunsmith forum, post up some pics.

the 125 would be right close to the 7.65 argie case.
a 308 is in the 010-015 zone [x51]
an x57 is in the 225-235 area.

Also could be a 7.5x54 French. But if the .300 Savage case is slightly fatter than the chamber, then a short-chambered 30-06 wildcat may be the answer.
