Sabotloader, Thank you for that info! That makes good sense and i can see how it would definitely work!! But I wonder how this would work with real blackpowder, or a sub like Pyrodex? A blued barrel will start to rust fairly quickly after being shot with real BP, and I've heard Pyrodex is worse yet? I have no experience to speak of with the Pyrodex, i just recently bought a can of Pyro P to try like Idahoron uses. Swabbing would obviously help a TON, but what about in the barrel Grooves, and the Snail, Patented Breech/Powder Chamber of a Sidelock? I use the blue windex with ammonia as well for my swabbing between shots, I actually mix mine 50/50 Blue Windex/91% isopropyl Alcohol to aid in faster drying. The only Montana Extreme product that i have used is their bore polishing compound and it is REALLY GOOD stuff!! (Would be their Equivalent to JB Bore paste) I will have to get some of the Montana Extreme bore conditioner and give it a try. I Have been wanting to try their copper remover as well in my Centerfires
