is a little copper OK?

i've had a 1962 rem 700 .243 rebarreled to a 21" stainless hart .308, .750" at muzzle.
maybe 200 rounds through it. it was shooting mostly in the .8's moa.
it showed copper at the muzzle after each session of 4 five round groups.
after each session - i throughly clean with jag, patches, butchs' and then hoppes, till patch comes out almost without color- no brush.
last two cleanings i just ran some patches with hoppes, very slightly green then almost colorless. then i got one group of five shots as .235moa, the first session and .260, the second session(using ON TARGET soft ware). best groups i've ever shot.

should i delay the cleaning a bit longer as my barrel seems to like copper?
 
I'm sure not an expert, but I think that a person could go completely stand in the corner and talk to the walls crazy if they tried to get every bit of copper out of a barrel. A lot of copper isn't probably good, but if your barrel shoots well with the way you've been cleaning I sure wouldn't change anything.

If you leave Hoppe's (#9?) in the bore and run a wet (with Hoppe's) patch through that doesn't come out blue or green or whatever in a day or two, you probably have a barrel that's not a fouler that doesn't need a bunch of messing with.

JMHO though.
 
Barrel Cleaning

I like the barrel cleaning regimen of Jackie Schmidt of Texas who I believe to be a world class shooter. When asked if his barrel was absolutely clean he responded that it probably wasnt but that it was clean enough to set records. Never forget that the first thing we do with a clean barrel is to foul it a time or two.
 
if its shooting groups your happy with, then its okay. some barrels are just prone to fouling. i own one rifle with a barrel that looks like a copper mine after 50 rounds, but it shoots very well.

I believe sometimes a barrel can be too clean. Have you considered moly or danzac? You can put more rounds through before cleaning is needed. Just don't go overboard.

Yes, a little copper is just fine. You will probably notice that after a major cleaning of the barrel, it doesn't shoot right for a few rounds. Think about this; the factory barrel will have imperfections, a little copper helps to smooth it out.

Tony,
Until I bought a borescope, I was cleaning far too much. The important thing is to keep copper and carbon from layering, you don't need a squeaky clean bore to accomplish this.

KG-12 Copper Remover

If you want the copper out get you a bronz bore brush and some KG-12 soak the brush and run through about 5 times then patch the barrel one time. No more copper. This stuff is majic, best I have ever used in my lile. Check out this test at link below.
