Ive found a huge advantage by weighing BH209.
No powder loss and its incredibly easy in a RCBS Chargemaster 1500 Combo. I tell it how much and how many charges i want. Press a button and go. Each time i place the pan back on the scale, it fills it up again until i have all my charges.
It does not get much easier than that for loads that vary by less than half a grain.
