Wrong.
"Pig iron is an intermediate product of the iron industry, also known as crude iron, which is obtained by smelting iron ore in a blast furnace. Pig iron has a very high carbon content, typically 3.8–4.7%,[1] along with silica and other constituents of dross, which makes it very brittle and not useful directly as a material except for limited applications."
Sigh......
"Pig iron is used for making steel and pure iron units. It has very high carbon content along with silica and another constituent of dross. Pig iron made from smelting iron inducts with the high amount of carbon for further processing steps."
"The name 'pig iron' originated in the early days of iron-ore reduction when the total output of the blast furnace was sand cast into 'pigs' —a mass of iron roughly resembling the shape of a reclining pig."
"Chromoly steel is actually alloy steel grade 4130. The “30” at the end of the grade number designates that it has approximately 0.30% carbon by weight. The added chromium and molybdenum help to give the steel different properties from its mild steel counterpart, AISI 1030, even though they have the same percentage of carbon."
Now, the subject of this thread is about heavy scopes that dial reliably.
