I will load my flinter on Christmas night for the following day's start of late season ML. I will keep it loaded until the end of the season which is sometime late January unless I shoot at a deer (or coyote) or if I suspect the charge got damp. Which is a good possibility during a PA winter. If any of these two scenerios occur I will clean and reload it. I've been doing this since around 1970 when I used my flinter during the regular rifle season prior to a ML season and never had any corrosion issues.
