Wow, 8 hours for a chamber. As I said, I don't know Mr. Griders, but I do know Al Warner. I have to ask if Mr. Griders knows that you are speaking on his behalf to the world and proclaiming that it takes him 4 times longer to chamber a barrrel than other "top smiths"? Again, I have heard from several sources that Mr. Griders puts out a fine product, but please forgive me for suggesting that you may be somewhat mistaken or possibly leaving out some supporting info.
