Just picked one up for an amazing price. All I can say is "WOW!!". How did I manage to go so long without one?? Charges are thrown as input with +/- 0.1, exactly as advertised (I cross-check every 3 or so charges on the beam scale).
Truly a must-have for rifle cartridges (too slow for pistol). I would have paid the full MSRP for one.
