Almost perfect

Once I figured out how to use this tool, it has become indispensable. I do have a bit of a problem getting tool set properly to measure the distance to the lands...there seems to be a fine line between tightening the set screw enough that the extractor will grab it and tightening it too much so it is really jammed into the lands. It's necessarily small size makes it hard to grip when tightening the screw. But once its set and you are getting repeatable measurements you have a reference point for the touching-the-lands seating depth for a particular bullet. Every cartridge I load goes into this tool to check the seating depth. And every case that goes into my FL sizing die goes into this tool to double check my shoulder bump. I would not be without it!
