For you flintlock hunters, how often (if at all) do you reprime the pan? I find myself constantly fussing over my priming powder. Is it fresh enough? Is it positioned evenly in the pan? Is it clogging the vent? Should I keep the gun level at all times? Am I being paranoid or is this what will help ensure that my gun goes boom instead of click (or whatever noise a flintlock would make if it misfires)?
