I used the same kenitic puller for about 35 years and one day it broke. So now I have an RCBS one and it works fine too. I have used it to remove bullets from military 30-06 ammo. I wack it on a piece of railroad rail.

My original (I think Lyman, but I'm not sure) one had little clips that you slipped into the extractor groove or washer like things for rimmed cases. The RCBS has a universal gripper but it does not work so well for belted magnums. It does work, but it can be tedious.
