I use my Lyman Lubri-Sizer and standard H&I dies. I reduce the bullets .002" per pass. i.e., I take them from .312" to .310" in the first pass and then to.308" on the second pass. I use a round nose top punch that reforms the lead nose on bullets that have them...... helps them feed through the mag better IMO.

IF you are shooting them in an original Luger, you may want to stay at .310" as the original pistols used a nominal groove diameter of .310 - 312". Newer pistols have seemingly gone to .308" groove diameter as standard. However, be certain that your chamber will accept the cartridge when loaded with the .310" bullets... newer pistols in particular are not likely to.

Some of my original Lugers will take the cartridge when loaded with .312" bullets depending upon the thickness of the case necks. Winchester is thinner than Remington. I have reduced Remington case necks to .008" thickness and used them with .312" bullets.

When I first began reloading for the .30 Luger, cases were nearly impossible to find so I made mine from .223 brass. Reducing neck thickness was manditory so I bought a Forrester Trimmer. It's slow but very good and it still comes in handy now and again.
