What are you saying about patches getting stuck?

I have a T/C Renegade, just a regular hammer gun. After several shots, fouling accumulates in the breech area, and if you run a patch down all the way, it will tend to get stuck. So, if that's your problem it is normal. BUT, you do need to thoroughly clean this area. I do this by running patches down gradually, a bit further each time, until the breech is clean. I'm sure you did something along those lines too.
