I do it a little different. I add an extra step but it has worked well for 20 years and I don't even think about it anymore. I use an old case with dead primer still in it. Something bigger than you are reloading, I use .375 H&H. I drop a load into the case from the powder throwcase held tight to bottom of powder throw, then dump into the pan on the scale, while the scale is settling I put another load into the case and set it on the bench. Trickle the last few grains into the pan on the scale with a trickle charger. Pour thru funnel into primed case put scale tray back on scale and dump the load in the large case into the scale tray. Load another charge from the powder throw and continue for 50 rounds. Work way better than it sounds and I can really get into a rhythm this way Hope this helps. Smokey
