I bought a .36 bobcat last week and tried to clean the bore over the weekend. I have a few .36 jags that don't mic the same diameter, so I tried one with a patch wet with water just to test the fit. It seemed a perfect fit, but down at the breech end it felt like it went over a lip of some sort and now its stuck. Does the bobcat have a step or enlarged chamber at the breech end? It didn't get tighter when it went over the step so I dont think it can be a powder chamber smaller than the bore. I squirted a bunch of Break Free in the drum and stood it muzzle down overnight to soak into the patch but it still won't budge no matter how I try to work the rod. I pulled so hard once that the rod's handle popped off. Its not stuck from being too tight but because its snagged on a lip or something at the breech end. How can I get it out?
