I use a cordless screwdriver and 0000 steel wool to clean all my cases and for neck turning works great!I have been skinning the cat another way by using a Sinclair case holder on my Dewalt gyro screwdriver and pushing the rifle case into my hand tools mounted in a wood block. I also drilled a hole in the block to stuff fine steel wool in to spin the case neck in to smooth things up. I can also put my primer pocket uniformers in the driver to clean the pockets. But of course if I was starting fresh the prep centers look great.
