What exactly did the companies do to make a shotgun barrel "rated for steel"???? Unless they somehow made the steel stronger or thicker or harder or whatever or whatever, I wonder if they did anything other than quit taking the easy route on their guns with the advent of steel and simply say they were rated for it. Some of you with a lot more knowledge of metallurgy than I will probably have an answer to the question of this doubting Thomas!!
