I used to have one of the old sky screen chronos, but they dont work indoors. So I recently broke down and bought the new Garmin Xero Pro. It works indoors and doesnt record the guy next port over. Buy once cry once. I have Lee Loadmasters with ALL the modifications and they work perfect. But I dont use them in full progressive mode. Once all dies are set up, I manually load a case and bullet. Add case and bullet...pull handle...one completed round. Repeat. I go slow. I am proud of the effort I put into these rounds.
