[QUOTE="NZ Longranger, post: 614496, member: 14"] KG12 is not ammonia based, and is said to be harmless to barrels. You never need to soak overnight, as it removes even the most stubborn copper deposits in just a couple of 5 or 10 minute soaking. For 99% of barrels we've worked with in the last 6 months, one 5 minute soaking has removed all copper. We have a bore scope and can tell you exactly what we've been seeing, all copper gone after one 5 minute nylon brushing and soaking. We have only had one barrel that we had to do two 5 minute applications, and that was particularly bad factory barrel. I cannot tell you just what the active ingredient is, someone else maybe able to do that. I do know as I said that it is 10 times faster at removing copper than Cu+2. Greg [/QUOTE]
