I love the Hornady setup, I have the comparator set, then the headspace shoulder gages (use the same insert) and I also use the OAL tool thats part of the set up, all work flawless and make it easy to set up the proper OAL and more importantly how much to bump the shoulders back with the body die.
Now this thing is something on my wish list
