Thanks cayugad,
I appreciate your help and input. I sent an email to GM, but they
never replied. I had much rather hear from a fellow shooter
on the subject anyway. My current TC barrel has lost it's accuracy
considerably. I noticed in some of your post you shoot a wad
behind a conical. How do you determine which wad to use with what
load? I thought I might try that before buying another barrel.

Thanks again.
