I agree with chipmaker.  A 40 ton press would work much better.  The arbor press, even with the arm extender, was marginal.  BTW, after using the die & press method, a primer pocket reamer may be necessary to restore the pocket diameter.

That's an innovative technique for someone without a press.  I would have never thought about using a vice.  I'll have to try it - may even work better than the arbor press.

Gentlemen,
I use the machine vise on my mill. I take the handle off and use a torque wrench and a socket to tighten the vise to the same ft. Lbs. each time. Reforming is very accurate that way. I found too much pressure can make the primer pockets loose. I need .080 rim thickness for my Sharps Creedmoor.

Interesting!

Here's my process for increasing the rim thickness after others have suggested the use of a mill vise and torque wrench. Thanks!
This is a Kurt 6" vise and I use a torque wrench set to 55 ft-lbs and this reliably increases the rim thickness by 0.005" in just one pass. The cases are virtually unchanged in other areas. I do check the primer pocket depth and maybe something like 0.5 mils is all that I cut out.
This is a pretty fast process now and gives one the ability to virtually go to 0 headspace if desired.
