1sailor--Again, not to argue, but many turret presses are capable of failing to advance. Although personally, I worry more about an under-charge than a double-charge.

On either press, placing a bullet immediately after charging is a good idea.

I usually weigh the first 10 or so, sometimes more, and then every 5th or 10th after that, depending on a few things--what the powder is, how often I've loaded that particular powder/charge combo, etc.
