Wow, Thanks for the feedback guys, this being my first build, it was full of "trial-and-errors"... but in the end it just made the final product that much sweeter! I'm taking her out tomorrow morning for her first range session. Should be a great time. I went on McGowen's website and found a useful guideline for proper barrel break-in procedure. I'll be swabbing my barrel looking for copper fouling after each shot through the first 10 rounds or so. If it looks good after that, I'll check it every 5 shots or so until I get to about 50 rounds. If no issues pop up, then I'm home free and I'll just be cleaning after each full range session.
