Is this rust??

Rifle is my father in law's 300 Win mag, he hunts with it yearly and noticed this. What is the safety way to remove or clean it? He's tried a normal brush going from the chamber to bore.

NO, it's cooper fouling. A thorough cleaning with [Insert] cleaner of your choice.

cooper fouling.

That would be my guess too based off the picture.

That's what I thought from the pic too.

I have a hunting rifle that hasn't had a round put down the barrel in about eight years. I try to take it out if the safe about once a year and give it a quick cleaning and wipe down. You should see how green the patches come out of the barrel from the copper.

Don't overscrub when trying to get out every speck of fouling. You can create as many problems as you solve by "over cleaning". Every bore will have copper fouling in it...you'll never get it all out.

I'm a big fan of the KG product line. It is non-ammonia based,and works very well. It does mean that you need to pick up2 or 3 of the other KG products, but it is well worth the expense. It is what was recommended by Noveske for their spr barrels and I use it on everything now.

This x 10.
Most rifles shoot better with a touch of fouling anyway.

Yes, I am pretty sure we have all heard of a "fouling shot".

I keep my firearms clean, including the bores. But, I don't over clean the bore. I usually run a wet patch, a dry patch, another wet patch, and one more dry patch and call it good.

Oh, and in case your buddy doesn't know any better, one of the worst things you can do is coat the bore with oil and then fire a shot. If he chooses to store the rifle with an oiled barrel, make sure he runs a dry patch through it before he takes it out to fire it.

Looks clean enough to me. Clean the chamber and action of carbon, light oil of choice, put it away.

try that foaming copper solvent. Squirt it down the bore and let it sit for the recommended time. Worked great on a .22 of mine.

Sweet's… it'll get all that copper out in no time. Clean well after using it before you store the rifle - it's a bit corrosive.

Sweet's does work. But the stink is as bad as anything ever made.

Seriously, it's fine… Just shoot it and stop worrying about scrubbing the piss out of the rifling. Clean the chamber, clean the action, re-oil, done. Leave the rifling and throat alone. It will be just fine and live longer.
