I purchased some 7.62x39 dies and brass sight unseen, and many of the cases have this step in the neck, as in the left and right cases in this picture.



Is this from the previous shooter resizing them for .308" bullets instead of .310"?

Will the necks iron out in a full length resizing die?

I would say this is most certainly not from being resized to .308.

I can't say what it is.

I would try FL resizing, it should fix the issue, however I wouldn't be surprised if it resulted in neck splits.

They were fired in a Russian Saiga or Vepr rifle that had a barrel made for legal civilian use in Russia. The step in the chamber neck is to identify fired cases as coming from a civilian rifle and not from an unregistered military rifle. This is the law in Russia.

Outstanding! Awesome info I've never heard of before.


Thanks for supplying it.

I have a Saiga that produces brass that looks just like this, it is true.

The Russian rifles must use a much smaller diameter bullet than .308/.311 or the chamber neck behind the .311" bullet is opened up to allow this expansion to take place. If that's the case split necks are almost certain at the neck shoulder junction.

Its the latter, the chamber is opened up.

I really don't see it as being a problem or causing split necks. If the brass is fresh it should size back down without any problem.

I guess you are not too familiar with calibers like .338-06 and 35 Wheeling. Both are made from 30-06 brass and work very well. Going from 30caliber to .338 looks about the same as the step in the photos posted. Now imagine going up to 35 caliber.
