I have a pair of Harrell's Premium Powder measures. I got frustrated with how long it takes for the RCBS to drop a 40g charge so I pulled one out. It's faster and not accurate to 1/10th grain. It over and under dropped a couple of 10ths intermittently but frequently enough to put it back. The RCBS does the same thing. I think they all do, even the Prometheus.
I've used a stainless steel teaspoon to drop powder into the pan on a scale. It's surprising how soon you get a feel for how a powder flows and what each piece weighs. I've heard of more than one person using Lee Powder dippers to drop a charge then trickle up.
