For pistol: Practice rounds are done with RCBS powder measure with every 50th or so round weighed. I do a few thousand a year like this. For HD or max loads powder is dispensed through my RCBS Chargemaster. I do less than a few hundred a year like this.
For rifle: All my rifles are bolt action sporters and are used primarily for hunting and fun target shooting. Each reload is made on a single stage press and every powder charge is weighed, either with the Chargemaster or beam scale. When using the beam scale I'll use the powder measure and then trickle. I reload about 500-1000 rounds a year for rifle.
