Well that's why I spoke of this process as a personal way of cleaning and not adding it as a suggestion. Originally I was only commenting on the amazing amount of dust and sand I've had accumulate in my rifle in the past. And I totally agree with using brake cleaner. But after this past weekend and 720 rounds later I had tons and tons of carbon built up inside the barrel extension and it needed just that extra bit of scrape to get it out. I was shooting Tula, and the last thing I wanted was Tula carbon built up on my $400 noveske barrel.
Use solvents, do not scrape! Is this really rocket science? Montana Copper Killer works extremely well. Take the easy, smart route. You are obsessing at this point.

Holy smokes...me and the Dude agree on a point under the cleaning/maintenance category.
Letting your bolt, carrier, and other broken down parts sit sprayed thoroughly down with Hoppes elite/mpro7 for 10min and then a toothbrush will totally clean them up. No need for any kinda of scraping and I'm not jumping on the previous poster just for the record.

The problem with scraping is that to actually scrape the carbon off, you usually need metal. I ****ing know, did it enough at Horno and Las Flores for 8 years. Scraping precision fit metal surfaces is a bad idea, it alters the dimensions. It's also a waste of time. Soak it in solvent, scrub off every 500-2k rds. Lube your rifle heavily, punch the bore when accuracy drops off, and shoot more, clean less.

Ok, let me rephrase the "scraping" part. I'm not scraping, I'm gently and tenderly picking the caked on carbon that will not come off on its own in an inaccessible place. The pressure I am applying when I "scrape" is more than likely less than the pressure applied when spinning a chamber brush to get the carbon loosened in the barrel extension.
If Im out of BC I use simple green with water. Works great as long as you have a compressor.
