Same here, if it's fired, it's completely broken down, cleaned, and lubed...period.
After getting into muzzleloading, and reading everything I could get my hands on, the common theme was always the speed at which corrosion could occur after firing a ML...so I made the
commitment to myself then and there that when I got home after firing a rilfe, I would not even sit down for supper or a cup of coffee until I had completely broken down, cleaned, and lubed the rifle.
(Plus, even you dared risk it, there's always the chance that something unexpected could come up to distract you away the next day or so it might then sit there 48hrs, 72hrs, etc, before you might get back and clean it).
So for me, if I fire it, I clean it...just like getting home with a tired out dog after hunting all day...the dog gets taken care of first, then I take care of myself.
I have some TC Hawkens I've used for a dozen years now and am proud to say that they're still in mint condition and accurate as the day I bought them
