Was wondering if olive oil would give the barrel the protection it needs?
No.............
It will gum up. It will not protect against rust either. In a breech loader it will foul the mechanism into a non functional state. When cleaning one, I usually envisioned some sheppard using his olive old to cook, his hair, his rifle, whatever. Then the rifle is so gunked up it won't even fire. So he takes it the the gunsmith for cleaning. As a patch lube, I have not issue. heck, spit works too, a pretty low bar.
Olive oil is fine for salads and cooking, not guns. Forget olive oil.
