I always store my guns pretty heavily oiled. Not that it is necessary. I would just rather have the extra peace of mind. 2-3 days before the hunt I start the process of swabbing it out. Every time I pass it or so for about 2 days I run a dry path or two down the bore. Again, not that it needs to be this much. I wipe down the lock with Zeiss optical wipes and ESPECIALLY the frizzen and pan. I then wipe off the the same areas with a clean patch. My one fowler, built by one of our friends, is as reliable as an AK unmentionable so I don't think I have had much opportunity to see the difference anyway.
