This thing works great and is a real time saver. The only problem I have encountered is primer pocket reaming crimped brass. It's difficult for me to get a consistent cut without it being too shallow or deep. I made a depth stop out of an old case. I cut it with a tubing cutter and used a table top disc sander to get the stop height. I sanded it a bit too much and put the washer under it. The 1/4" ID washer fits the tool base perfectly. This has saved me a lot of time and gives a consistent cut.
