Awesome tool!
I've reamed the inside of primer pockets for decades and needed a new one. I was accustomed to a model that based the reaming on the inside of the case and not on the case mouth like many designs. This one does not use the case mouth which makes it quick and easy to ream any case. My old one used a cone to center the shaft in the case while this one has specific stepped diameters on a conical shaped guide which works nicely. The handle can be unscrewed and I can attach it to an adapter that goes into my cordless screwdriver to power ream. Or you can easily ream a few by hand with the provided handle. The inner cone that the reamer cuts is very appropriate and very clean. It also makes the flash hole uniform if it's not already. It's exactly what I was looking for to replace my old worn out reamer. Much appreciated.
