I think I finally got Copper removal down to a somewhat faster removal method. No doubt it's been done before or some type of it's variation. Ran out of my favorite KG12 Copper remover solvent which I still like a lot , but it does have 2 down sides it's burnt orange in color and it beads up on patches it's not a good verifier to tell if copper is totally removed. It's the only solvent I've found that actually eats copper when I tested a bunch of other copper removal solvents including bore tech elinimator, various others, including straight janitor grade ammonia. I've been using JB bore cleaner for a number of years and never really gave it my best shot, relying more on chemical Removers and nylon brushes and copper/brass free rods and tips to eliminate any false positives that mark blue on the patches. I do make my own Ed's Red carbon removal solvent one reason I use a lot of bore solvent so it made sense to make this in bulk, Hoppes # 9 is another good solvent and the one I used on these last 2 fouled rifles.
Run a bunch of patches with Hoppes # 9 down the barrel and get all the crud and carbon fouling out, run clean patches down the barrel to clean and dry, next run a couple patches of bore tech eliminator down the barrel and let sit a couple minutes and then run a clean patch down to verify HOW MUCH COPPER BLUEING is on the patch ( this is your verifier ) You can also use any of the better Ammonia based solvents and do the same Verifying blue test. I just happen to use Bore Tech mainly because I feel it's safer to use than high strength ammonia based solvents and accidently getting it into places that you don't want like the blueing of the gun, stocks, plastic parts, etc. I think almost any cleaner in the wrong place can do damage, being careful is the word of the day. I do use a bore guide & one piece rods. Follow instructions on all solvents and cleaning instructions, oil the barrel after cleaning, the normal stuff, etc. I got more aggressive this time, I used a slightly undersized heavy duty bronze brush, then cut & wrapped a cotton cleaning patch around the bronze brush about 1 1/2 times around and then rubbed JB bore cleaner completely around the patch, then I took some copper remover solvent I used bore tech and dribbled some on the JB soaked patch then ran it down the barrel 30 or so times and then ran hopes # 9 down the barrel to clean out all the crud, once cleaned I ran a couple patches of bore tech eliminator down the barrel to verify any blueing on the patch and yes it came out fairly blue heavier in the rifling so I repeated 30 more strokes with jb paste a new patch around the bronze brush this time with hopes copper terminator solvent same thing after 30 strokes, but less blueing on the patch when verifiting with bore tech eliminator solvent, repeated the procedure 30 more strokes using bore tech and JB paste on the bronze brush/clean patch routine. This time verifying with bore tech no blue on the patch at all. Cleaned really good with Hoppes # 9 and re-verified just how clean this barrel is with bore tech again and let sit a couple minutes and ran a couple more clean patches down and NO blue coloration on the patches what so ever. Kroiled and Micro oiled the barrel. I could have used other copper solvents this is what I happen to use this time. I did this same routine with another rifle that you could visually see with the naked eye a copper tinge coloration in the barrel, after cleaning all copper is out as far as I can tell. I do have some non abrasive JB Bore Bright for polishing the barrel rifling to a supposed smoother finish whether it works or not I don't know yet or it will lessen any copper fouling down the road is to be seen. I do have one concern in that aggressively running brush down the barrel that many times , how hard on the barrel is this procedure and is it doing more harm than good ? I don't know at this point so if anyone is going to try what I did to get the copper out of your barrels it's really on you whether you want to be this aggressive on barrel cleaning and possibly ruin a barrel just from over cleaning or improper cleaning methods. Sometimes I think you can get a barrel too clean and then needing to re-foul the barrel to get it to settle down for best accuracy.
