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.
