Second on the K&M. With the handle or in a drilldriver. My shooting buddy saw them and borrowed them and thought whey were great. I gave him the large and small then ordered a new set for myself.
He77, my very old Lyman uniformer works for me in a drill/driver. I doubt there is no real difference in any of them that way but one made of T. carbide would be good if you plan to do a LOT of cases.
The method I use also.
