Re: Chamber cleaning: what's your method
The biggest trick to cleaning a chamber is not letting it get "dirty" in the first place. The simple function of firing rounds puts enough "dirt" in there without introducing anything unnecessary. My chambers are afforded the greatest protection I can give them. I'm very religous about keeping my brass clean, and never chambering a round that could introduce dirt to the chamber, or otherwise cause it damage. This also relates to keeping my dies in perfect condition as well. In the field, I really don't care what happens to the rifle, but the chamber, the bore, and the ammo are sacred.
To actually clean the chamber, the best thing I've found is to take a cotton shotgun bore mop of the appropriate size, and attach it to a pistol cleaning rod. I made my own with an old rifle rod cut down and a file handle, with the handle glued on so I can twist it. a .410 will do great in a .223 chamber, and a 28 gauge will clean a 308/30-06 based chamber.
I'll take a pair of sharp scissors and trim the front end of the shotgun bore mop so that the whole thing resembles the shape of the chamber to be cleaned, which allows the front end of the mop to be forced into and clean the throat. I soak this mop down with carburator cleaner, or brake cleaner, force it into the chamber as far as it will go, and simply twist it a few times in the chamber, holding the muzzle towards the floor to keep any excess liquid from running down into the stock bedding.
Using a second dry mop made the same way dries the chamber and finishes the cleaning. If the lug recesses need cleaning I spray a little brake cleaner in there and blow the hell out of it with compressed air. From there it's a simple matter of following any normal routine of cleaning/oiling the bore/chamber.
To clean the chamber mops for use at another time it's as easy as spraying them down with the brake cleaner or carb cleaner, using the force of the aresol from the little red tubes to turn the mop white again, and then shaking them dry.
It all takes longer to talk about than it does to actually do it.......
