The Chargemaster is my single most valuable reloading tool. I have it set up between single stage and Dillon 550. For the precision ammo, it throws and weighs my ammo accurately. For my bulk ammo, it's my QAQC check station. On stage three right before I seat bullets, I'll pull out a case at random and weigh how much powder was thrown. If it's within my acceptable range, then I dump the powder back into the case and put it back into the 550. One thing: for the Chargemaster, get the aftermarket powder catch with the built-in funnel. I superglued a quarter underneath it to provide enough weight to reset the scale, and the funnel eliminates and extra step. I also use the McDonald's straw trick so that my powder trickle is more precise.
