I load a bunch of handgun loads, mostly 44 magnum, 45 long colt and 45 ACP and I use a 'Little Dandy' powder measure (thrower) because the charge is much smaller than a bottleneck load.
I fill my Little Dandy and set it to repetitively throw the charge I want (usually takes about 10 consecutive throws to get it repeatedly at the same amount). After I get it throwing the correct charge weight, I just charge my cases in bulk, checking every 10th case on my beam scale (takes about 15 seconds). Keeping the Little Dandy filled to about the same level insures a close match on the powder throw.
I get a rack (usually 75 cases charged and look inside each one with a flashlight to check, again, the powder level prior to seating the pills and crimping the case mouth.
I've never used any electronic dispenser and don't plan on it. If I did get one, it would have to be an RCBS but it would have to be a gift from an admirer (wife).
I see no need for one.
I do the same with bottleneck brass. Just loaded 500 308's and 1000 223's exactly the same method.
