Had my T/C Impact out hunting over my Thanksgiving vacation, after being loaded for over a week (which I have done plenty of times) I discharged it and brought it home to clean it. I have always used Thompson T17 cleaner and barrel lube, of which I had run out of both. I have to order all my muzzleloading supply's, our of muzzleloading supply's is skimpy at best (and best is only during our 1 week season in October) in my part of GA and the closest I have found is about an hour drive. So I cleaned my rifle with warm soapy water and Dawn, brushed the barrel as always with a copper brush and washed agian with warm water only till I got a clean patch, I then run a dry patch through it repeatedly till it was dry and clean. An alcohol patch was run though to remove any possible moisture and a dry patch run through agian. I was out of anything to coat my barrel so I run a patch of Rem oil through it. When I went to load my rifle a little over a week later, I run a dry patch through it as always before popping a cap through it, Good Grief at the Rust!!!! I have only been shooting this rifle for 3 years (over 300 shots is a guess thinking about bullets I have bought), I have never fouled a barrel like this. What did I do wrong? The rust was like a soft brown wet rust, I cleaned on it for over 3 hours and I still have some rust it appears down the first 3 inches or so at the muzzle. But the rust that is there is not brushing out even with when I use pieces of a Copper chore boy pad in my brush. It is almost like I have browned the first 3" of my barrel. What did I do wrong and any advice on getting it out is appreciated. It still shots spot on as it is now, but seeing rust is driving me nuts.
