I am using Titegroup in a Lee Auto Breech Lock Pro with an Autodisk measure. I use Titegroup because it meters better than the Unique i was using before. In some of the early iterations of running it, I was arguing with the indexing mechanism. Sometimes the shell ejector popped loose and allowed a double feed into the case pusher, and I had to hand-cycle everything backwards. It took me a while to learn the quirks and rhythm of the system. But while I was moving that first set through, one (at least) got away from me. That's why I'm not afraid to scrap them and start over. I have done thousands of rounds in a single-stage press, where I can lay them out in trays of a hundred and verify the charge in each case. What I am doing now is re-mounting the press down to a level where I can eyeball every case before I seat the bullet.
