This is a Thompson Center Hawken 45cal barrel that is like new. The bore is very tight on this one. A .440RB and an OX-yoke .010 prelubed patch is all a fella can do. I have a Knight range rod with the t-handle that has a 45cal jag on the end of it. It's a nice tool for range loading and cleaning. This is a new barrel to me and I fired it for the first time today. Time to clean. Pushed a T/C 777 pre-saturated patch down the barrel. It was snug all the way down and there was no pulling the patch back out. The rod is stuck and I have pulled with over 200 pounds of pull. My body weight. No joy. I just sprayed a whole bunch of LPS down the bore to prevent any corrosion. This happened once before on a pristine Seneca 36 cal barrel and before I could find the tool too remove the breech. I damaged the bore with corrosion. Never want to do that again. What should I do?
