Copper

A J Christ
Recommendations for getting copper out of a 300 WinMag barrell. Scrubbed it with a couple of different brands of solvents that advertise it to be the very best for removal of copper and lead fouling. Patches still come out blue/green and looking down the muzzle you can still see a lot of copper in there. Short of investing in one of the electric machines, anyone have any good fast way sto get it out? The rifle has been shot a lot before it came into my possesion and it looks like it was not properly cleaned.

    Blue Wonder and a stainless steel bore brush works best in my experience

    I had bought a badly fouled '06 once and I put a rubber cap over the muzzle filled it with Hoppe's Bench rest and stood it muzzle down in the corner overnight next day I scrubbed it with a bronze brush and a lot of stuff came out, after dozens of patches it was cleaner than it had been in years. It actually turned out great. The guy sold it to me because it wasn't accurate, after this treatment it shot 2" groups at 100 with factory ammo. You might ask someone else though if this treatment is harsh for the bore.

    I just tried Blue Wonder for the first time. Cleaned an old Springfield rifle that hadn't been really clean in years. With 2 applications the barrel looked like it did when the gun was new. I used brass brushes instead of stainless. I think they are more gentle on the bore.

    You can get Blue Wonder from Allen Glore. He's a good guy to do business with plus he's one of us.

    A good soaking in either tetra gun or sweets 7.62 should do the job. Remove the barreled action from the stock and insert a rubber chamber plug. Let it soak for a few hours and then brush it out with a brass brush. Should do the trick. Also may want to try 2 parts gum out carb cleaner and 1 part marvels mystery oil. This is an old benchrest formula that works pretty good.

    An abused barrel,..especially in a magnum will take some time to come clean. First off,..copper and powder fouling occur in layers. Your patches may start to come out green,..then go to black/grey which shows you are now into a layer of powder. The PSI exerted on the layers as each bullet passes through the bore makes the fouling almost as hard as the barrel steel. I suggest a good powder solvent and a good copper solvent.

    First go in with an aggressive powder solvent and a brush (bronze). Scrub and let sit,...re-patch and scrub then patch out. Now go to the aggressive copper solvent (sweets 7.62 being the fastest and meanest) Follow the directions and don't mix it with other solvents. After several applications of sweets,..go back to the powder solvents,..then come back to the sweets etc etc etc.

    I have taken OVER 60 dark blue patches from a 300win mag barrel just a month ago,.before the barrel came clean down to bare metal. this was using sweets!!!!!! You may find that after the cleaning,..the barrel will re-foul quite quickly,...this is a tell-tale sign of erosion from powder and fire,..and can not be fixed without the barrel being set back and rechambered. If it does not foul quickly,..then you still have a barrel with plenty of life left. You will also be able to tell by how the patch feels as it passes through the first few inches of bore in front of the throat area.

    why chase the game when the bullet can get em from here?....

    The bore didn't get that fouled with one shot and it won't come clean very easily either. JustC hit the nail on the head. Whoever had the gun before you did not take proper care of it. There are most likely several layers of powder/copper built up in it. Every time he shot it without cleaning, he added a new layer of build up. By the way, even with an electronic cleaning unit, you would still have to clean it layer by layer. There is no short cut that I know of. The absolute quickest way is to get some JB Bore Cleaner and use it as described on the instructions. Even this will take a little time-not a hit it and forget it approach.
