Have you tried chambering a re-sized 7.62x51 case?

You could spray a loaded cartridge with Engineer's Blue, chamber it as far as it'll go, and then check where it's hanging up (where the blue has been rubbed off). That will give a good idea of where the problem lies.

It is possible this brass was fired in a machinegun. Machineguns have very generous chambers. This is needed to insure reliable chambering at rather high feed rates.

You may want to try a "small base" full length sizing die. You may also need a rather stout press. Read little or no flex or streach.
