They were very consistent .310" diameter, though I didn't measure them all.

I had 2 of those big Russian spam cans full of 7.62x54R military ammo (ordinary ball) in packets of salmon-colored paper tied up with string.  More than 400 rounds per can.

Exercise #1 was to see if they would all chamber in my M39 or SA-marked 91/30.  They would not all chamber. 

Exercise #2 was to pull about 250 bullets and measure diameters.  Very few less than .310".  But many were .311 a d .312.  Some were as large as .315.  Cartridge cases with the fat bullets would not chamber in either of my rifles.

One could run Russian bullets through a Lee push through sizer, but I prefer to use the throat of the rifle.  My K31 has a very tight .3055" groove diameter barrel, but it shoots .308 bullets very accurately.  As long as load development is started low and worked up, and the load is used in the same rifle, I don't see a problem with slightly oversized bullets.  I have a bullet I pulled from 7.62x54R, Silver Bear ammo.  147gr, but it is just as long as the 173gr bullets I have been shooting.  It strongly attracts a magnet.  It is .3108" diameter.  A .315 bullet is about max diameter for my Krags.

The fat ones do well in my 7.7 Jap.  A rifle for every type of bullet.
