How many dialing scopes have you used extensively, say for years of up and down?
Also, did not know "pig iron" was used inside 21st-century scopes.
John, you're being kind of literal......
I don't "extensively" use any my dialing scopes, and not sure what you mean by up and down. I change loads and adjust for wind left and right often enough, too
You may not be aware but most of the various steels start out with pig iron. Can you tell us what materials are used in 20 oz + dialing rifle scopes to make them that heavy?
