Just bought one. It sucks. The first piece of brass seemed to ream ok. Went to do the second one it was already not cutting. Had a good look at it and at first I thought it the edges were filled with brass. Nope the thing is stirped out. I tried to prime the first piece and sure enough, it isnt big enough for the primer. What a piece of crap. Almost though I went shopping at princess auto for tooling of something. I also bought a lyman chamfer tool. That one works awesome. Nicer to have a handle instead of using the rcbs inner outer tool.
