All I will say is some of the things the Montana X-treme products have done are impressive. Like they have pulled carbon out of barrels I would have swore were clean. They leave a barrel smooth as glass when you patch. Fowling does not seem to stick to the bore, but then it did not really stick all that bad before. And so far it seems to be protecting the bore from rust.Also I want to test if the first shot stays with the group, rather clean or fowled.

So if this product will keep pulling things from the bore I was not aware were in there, and making it smooth and protects from rust, I might very well change to a brand different from Birchwood Casey. But I must add.. I am very happy with the Birchwood Casey products. So it will take some pretty impressive results.
