Can't get much better for what you are doing than Win231/HP38.
Level your scale and zero it. Then, without moving it, set your desired powder weight on the poise. Throw your charge into the case, then dump it into the scale pan. It should zero out again. Pour it back into the case and set the bullet.
The Pro Auto Disk is so consistent it is almost boring with 231/HP38.
I moved mine over to my LnL AP and it works just as well there.
