I load all my ammo on single stage presses. When I drop a powder charge into a case, I visually check the powder level in the case, then seat a bullet in it before placing it back into the cartridge tray. It's the best way I know of to avoid a double charge. Plus it reduces the number of times a case is handled during reloading. Think about it, you are not going to pick up a case with a bullet seated to drop a powder charge in it. But if you charge all of your cases before seating the bullet then it does become possible to double charge a case.
