Finnaddict.. that mixture you have listed looks a lot like moose milk which I use to lube patches when shooting roundball. This is not really the best solvent a person could use. Some even swab a barrel with the stuff but I am not about to swab a barrel with an oil base product.

Are you thinking of; M.A.P.

MAP is a solution that will clean off hard to get fowling but it too is not intended to clean off plastic fowling. If you want a cheap fowling cleaner that does take off some plastic and other fowlingthen use some kerosene, turpentine, denaturedalcohol or break cleaner (from NAPA and keep it and all that other stuff off your stock and scope) .

Personally I use Birchwood Casey Bore Scrubber. The thing is you do not have to use it every time you shoot. Only when you get a build up. Then all you have to do is dunk the bore brush into the solvent and scrub the barrel about ten strokes and it will remove the plastic, copper, and lead fowling. Be sure and wash the bore brush off under the kitchen sink. That bore solvent can play heck on your brush (why many of them wear out so fast). When I am not out to take the Plastic , Lead, and Copper fowling out of the barrel, I like a product called Butch's Bore Shine, or Black Off Rusty Duck cleaner. I buy the stuff at Wal Mart and it works great.
