Are you crazy, or just stupid?? Your attempts at justifying your treatment of shotgun receivers are reprehensible in either case. You obviously don't have a clue, and your incessant trolling is indeed becoming tiresome. When you take the time to learn the craft and can contribute meaningful insight into color case hardening maybe then I'll revise my opinion of you and your "techniques". You have taken chicanery to a new level, and I pity the folks you have bamboozled.
