Yip, the Track of the Wolf liner has a smaller diameter that the Jim Chambers White Lighting. I have not measured the Track liner but I will and let you know the size. I will bring a sample of both to your next shoot to show you. You have seen me shoot my rifle many times and know how reliable the and quick the ignition is. I log all of my shots since replacing the barrel and that barrel now has 3,427 shots through it and it still has the original Jim Chambers White Lighting touch hole liner installed in it. I have recently checked the liner and the next size number drill will not fit through the liner and that drill size is a #53 .059". Not all rifles will perform the same and on some I have had to increase the touch hole diameter due to slower that acceptable ignition time. There are many variables that cause this such as liner position in the barrel, the lock, lock location etc. Hope this helps you. See you Nov. 2nd.
