The military uses M-Pro7 products.
You probably know that some rifle barrels need a level of copper fouling to shoot well, others are doing their job again after a few fouling shots.
Mine are the latter, and I remove copper with every cleaning along with powder fouling; Wipe-Out foaming bore cleaner. Spray it into the bore, let it sit (overnight if very fouled), then patch it out. I'm lazy, and this stuff just plain works. Nothing else for the past three years.
