You don't mention calipers, a scale, or a flashlight. You probably have all three since you load handgun and everybody has a flashlight. First two are obvious. The flashlight is to run over your loading block verifying that you have powder in every case before you start seating bullets. That will also help you catch heavy or light charges (missed the funnel with a bit and it splashed into the others and all over the table....it happens) and if you run ball powders in small cases it might help you find a case or ten without a primer...that happens too... flashlights are also great for finding dropped bits and pieces like spent primers.
