Has anyone else here ever had any problem with flame cutting on their base pin? I have an 83 in .475 that hasn't been fired all that much, and the last time I clean it, I noticed that there is a slight ring being cut into the base pin exactly in line with the BC gap. It is slight, but none-the-less it's there. I am wondering if it has to do with the use of Lil'Gun possibly? After reading here, and having Mr. Baker tell me in another post here that Lil'Gun will cause me trouble, I will not be using it in my gun anymore.
