I have and use a Hornady Auto Charge Pro and it works very well and accurate as I check and verify against 2 other scales. Also, my original one started acting up and would not calibrate with the 50g weight giving me an ERR code. Called Hornady, they sent me a shipping label on their dime, and then sent me a brand new model on their dime as well. Superb customer service. And my old unit was 4 years old!
