I agree with you Miles. Many misfires are from poor cleaning, not from moisture in the air. I remember when we first got a muzzleloading season. Guys who knew nothing about muzzleloaders were having misfires on a regular basis. Many times I have left the woods at dusk and would hear the sound of guys firing their muzzleloader so they could go home to clean and reload it. I normally do not empty my muzzleloader until the season is over, unless of course I have fired it. There have been a couple of years that I left it loaded until a couple of weeks before the next year's season. It has always fired.
