I'm pretty new to reloading compared to a lot of people here, but here are a couple pictures and description of what has worked well for me so far.
When dispensing powder, I place my prepped cases in a cartridge box and work from left to right. I first remove a row of cases and set them aside so there is always a blank space between the full case I'm setting into the box and the empty one I'm pulling from it. After the charge is weighed and poured into the brass, I take a bullet and set it upside-down inside the case mouth before transferring the cartridge into the box. This clearly marks each case that has a charge it in, preventing both squibs and double-charges. In the calibers I reload (.30-06 and .22-250) double-charges are impossible without spilling, but I'm cautious about it anyway.
I dispense powder using the volumetric powder drop that came with my Lee Classic set, dispensing it into an old .30-06 case that has a messed-up neck from a time when I rushed a bullet seating and tried to press it with the bullet cockeyed. Using this case is a constant reminder for me. The only time powder touches the actual prepped case is after the load is weighed (I weigh each load) and 2 seconds before the bullet is dropped in upside down. For .22-250, the bullets are skinny enough that they can pass through the throat of my funnel so I drop in the bullet before I even remove the funnel.
