View Full Version : KG 2 bore polish

10-07-2010, 08:36 PM
I've got a new (5 months) Savage Varmint12FCV .223 rifle. I do mainly target shooting 100-600 yards. Some in competition, some in pratice. Shooting between 17 to 50 rounds each time. Guess since I've owned this rifle I've put a total of about 600 rounds through it. After every shoot I religiously clean the rifle. I use Shooter 's Choice for cleaning out the carbon, both with patches and a nylon brush, then dry patch. I then use KG 12 for getting out the copper. Removing the KG 12 with more Shooters Choice, dry patch until clean and finish off with an oil patch.
Today for the first time I used KG-2 Bore Polish, I could not believe what came out of my supposedly clean gun, with the KG-2. After 20 strokes, the patch was "black" !!!. The KG-2 is light gray in color, so I know it did not come from it. It had to be carbon build up, that could not be removed through "normal" cleaning. (see above)
My question is how often should I use the KG-2? and will using it too often damage the barrel?
Anyone else have experience with KG-2

Much thanks

Why would anyone clean an unchambered barrel blank.?? Well I have done that. If the
cleaners we use are harmless to steel, why not see what happens. J&B bore cleaner will
turn patches black as will Rem Clean. Use a brush and the liquids will get you some
green and blue

I was told in a conversation recently by someone who knows that the KG-2 was a lot like Iosso or Rem Clean. or I guess JB for that matter. All of them turn black in barrels rather or not there is carbon present. I have been using KG-2 lately and I have a bore scope so I can see the before and after. What I found was baked on carbon will come off quite readily when applying KG-2 to a bronze brush and stroking it through the bore a dozen or so times. This will equal 25 or more patches if that would be enough. Truly I don't get the patch only thing. The danged barrel is wearing out every time one lights the fire in it. If one want it clean they have to scrub it; especially after it has had the fire 50 or so time without cleaning it. What I haven't decided yet is how much one should take out. Perhaps if we have to foul them after cleaning we should just leave some in there. I believe one can clean too much thus inducing wear with the rods. RODS; another area that needs more study. I find that most rod guide, rod combinations don't work as they should = too loose.

Well Pete..... some of us do it because WITH A BORESCOPE we feel we don't need to stick a brush in :)

I use all kg products to clean my bbls.. I have a borescope and 2-4 patches with the carbon cleaner 1st, then 2-4 patches with the copper remover kg-12 worked back and forth in short strokes, then one patch with the oil, checked with the borescope and it is clean. This is the routine that I have come up with that works for me and my bbls. BUT the only way to know if it works is with a borescope. No brushes only because this works for me. Just my .02.

Talked to someone that knows about these bore shine products. Said the black patches are normal, even on a clean rifle. Some thing about a chemical reaction. Not to worry. Still not sure about how often to use the bore shine product KG-2

If your rifle was shooting consistently to your expectation before you used K2, why bother with it?

If your rifle goes right back into the money after K2 the same as it did with your previous routine, then maybe you could save it until accuracy changes & you figure that your barrel needs help.

However, many shooters use products like K2 to ensure that they don't get buildups in the bore & use them at regular intervals. As an example, I shoot F class & use JB Bore Bright sparingly as a last cleaning step after a match, which could be between 100 & 150 rounds.

My borescope tells me a different story with my 30's.

From what I have seen looking at barrels that are shot all day during a match without cleaning there is about 4 to 6" of carbon lain down on the lands. The more times the barrel is shot without intensively scrubing the carbon off, the harder it is to get off. The question is, how much of a build up is too much. perhaps there is no issue and perhaps the carbon never gets too thick but I doubt that. Just don't know.

I know that most folks need to "Foul" their barrels after thay are carbonless so how much is enough to leave in there?

You can't clean every 20-40rds?

I see shooting and cleaning sort of like Road maintenance. I will patch clean during the day of shooting, typically all I have time for, Every barrel has some flaws, by shooting, it allows a filling in of the pot holes and produces a consistant shooting rifle. ( smoother road) I never hold off to fowl, first shot goes in the same place as the last, providing conditions dont get me. After a match I will brush 3-5 strokes and wipe dry. I have shot coated and uncoated and never have copper showing on patches soaked with butches bore shine. Only blue after brushing is noticed. I might once during the season JB , only a gray color appears on the patch. I see cleaning as maintaining a controlled fowling of the barrel only, spotless does not seem to make any difference other than more sighters to get the rifle to seatle down. And a greater chance of me messing up the bore or crown . My 2 cents worth.
