[QUOTE="Dzaw, post: 143901, member: 7794"] [b]Hummers[/b] I have encountered this phenomenon... I have a theory on this, but I'm not entirely sure how valid it may be. See, industrial heat treaters, like most barrel makers (likely) use, typically aren't tooled up for small run precision treating to spec. More often than not, they take the steel grade info and intended application, and run it through an ANSI standard process in automated or semi automated machinery. While this typically results in relatively good consistancy of product, it may not be optimal, and the occaisional real hummer as well as the occaisional real lemon could be the result. By studying metallurgy a bit more deeply, and constructing their own HT equipment, I think a real improvement could be had by those who don't do this already. I could be dead wron in this. For all I know, these barrel makers do their own HT in house. However, if that were the case, I would expect that they would advertise and tout that fact as broad and as far as they do their machining excellence. As we say in the bladesmithing community, the best steel, shaped by the best smith, and given a mediocre heat treat makes a mediocre blade. Decent steel, shaped by an absoloute novice, and given an optimal heat treat makes an heirloom quality blade. The heat treating really is that critical to steel performance. [/QUOTE]
