Thought LBT Blue was decent?
I've used all 3 grades & it is decent. As for hard lube I've used a bit of Ballisti-Cast & if the bullets were sized properly the lube did decent. Is it the best lube for my sixguns? Hardly.
Is it worthless? Try shooting a cylinder full without lube, clean the barrel & try a cylinder full with LBT Blue Commercial & note the difference.
Like USSR1991 said check out White Label Lube. They are good people.
