Troutman10 - with the little information provided,I am going to have to guess. First off, I appears you shoot a Triumph. So it being an inline I hope you're not treating the bore with Bore Butter seasoning patches. The bore butter could be your real problem if that's what you're doing.

Bronko gave a good description of how to clean a inline rifle. If you were using bore butter and you did not do everything perfect, you run the risk of rusting your bore. Also bore butter will build up in your bore.

If you have used bore butter, I would suggest you boil the barrel. Get a tea pot and get it full of boiling water. Take the barrel outside, set it some where, and pour boiling water through it. The boiling water will melt the wax out of the barrel. It will also super heat the barrel so be careful and wear some gloves when you handle it.

After you have the bore butter out of the barrel, take a patch with alcohol on it. Swab the bore good. The alcohol will help displace any water that might be in the bore. After the alcohol patch push a couple dry patches through the bore. Check them and see if they are dry after they come out. When they come out dry, then with a quality gun oil saturate a patch and swab the bore. As the barrel cools it will suck that oil up into the metal.

Before you shoot next time, take a patch, apply some alcohol and swab the bore. The alcohol will take the oil out of the bore. Then a couple dry patches, pop a primer or two, and your ready to load and shoot.
