Deposits on crown after removing can

[Tim K]

How do I get this stuff off? I've tried all my solvents, and none seem very effective. I doubt this matters, but it's a TB 30-P on a .260 bolt gun. H4350.

Little steel wool, or scotch brite pad , after you soak the crown with (gun cleaner of your choice) soaked patch.

I use an old case with the neck mashed together as a scraper . Soak a patch in solvent and let it soak and then scrape staying away from the bore , it chips off in big hunks . I personally wouldn't use abrasives and scrub the crown , it's going to break down the clean sharp edge where the crown meets the bore which is the most important part . You'll be surprised the small affect the carbon volcano has on accuracy in a precision rifle .

[Tim K]

Thanks guys. It all came off adjacent to the bore so it's just a cosmetic thing. Damn ugly though.

[Hoser]

Just shoot it. It might look like smashed assholes, but no accuracy drop off.

The crown is the teeny angled ring-shaped area where the rifling blends into the muzzle face, not the flat recess some barrels have to help protect the actual crown from hitting anything. Think of the place a marble would make contact with steel if you balanced it atop the barrel, and that's where the actual crown is.

Carbon crud on the muzzle face may be annoying to a neatnik, but does not affect function any more than a splash of dried mud on the outside of the barrel would.
