Excellent web site, more to my question and the Remington law suit,

Interesting note,

"Carbon is the major alloying element present in carbon steels. They also contain 0.4% of silicon and 1.2% of manganese. The AISI 1140 carbon steel is a free cutting steel. It has high strength, and is combined with sulfur in order to increase its machining characteristics"

Could that be the problem right there?

California Chuck (Chuck H) knows all this stuff, I don't know why he doesn't post up.
