Sigh! I know, I know. I just like knowing this stuff. Been into things like this most of my life and marketing jabber just pisses me off.
The why and the wherefore is what makes the stuff work. I will research the product a lot more than most when it comes time to select new equipment or parts for my guns, motorcycles and watches. You can make an adequate cannon barrel out of Oak sticks with some brass banding, but that is not what I'd want for a precision rifle.
