I love this stuff. I have read or heard enough references of how great this stuff is. Yesterday I finally tried it out. I have to say am very impressed. It is so easy to use, and it sure pulled a lot of crud out of the bore on my old M96 (1914). I thought I had thoroughly cleaned this rifle before, as I typically soak, brush, and swab a bore pretty well. Foaming bore cleaner went even further. I couldn't believe the crap that came ou. It wasn't just the blueish residue I expected from years of copper, but enough blackening to make me consider filling the bore with foam again.
Looking through the bore later made me real happy. This old rifle now has a sparkling bore, that doesn't look 93 years old.
I need to buy more of this cleaner, and do all the firearms. I wonder how much crap will come out of my old 1891 Mosin Nagant.
