I've tried this stuff the last three times I've cleaned my T/C. Followed directions on the bottle (brush bore, squirt stuff in barrel, wait 5 minutes, apply to brush and clean some more, follow with dry patches). This is the most work I have ever done to clean a muzzleloader. The bore is never fully clean at the first try, I have to repeat a second, and most recently, 3 times to get my barrel o.k. It took some soapy patches and Breakfree CLP to cleanup the rest. For $12 a bottle, I expected more. IMHO, it is no better than hot water. I can clean my barrel in half as much time with hot, soapy water. FYI, I am using triple 7 in my gun.
