Hi all,
I bought a kimber gold match 1911 a few months back, new from a local gun shop. When I took it home, I noticed that the barrel seemed a little dirty, there was visible crud in the edges of the grooves. I gave it a good cleaning, a really good cleaning, but was never able to remove this residue on the edges of the grooves. I have since put a couple of thousand rounds through it, thoroughly cleaning it every 250 rounds or so.
It works perfectly, has great accuracy, I had a couple of ftf's at first but I hear that is typical.
My problem is that no matter how much I clean the barrel there is still this crud on the edges of the grooves in the barrel. I don't see this stuff in my sig 223. Am I being too picky? How could I remove this? I have a bore snake, bronze brushes, shooters choice solvent, spray cleaners, etc. nothing seems to remove it. any advice would be welcome
