I just bought an old Featherweight in 7X57 and noticed it had rust in the chamber. Can anybody tell me how to get rid of this rust.

Depends how much and how deep.You might wrap steel wool around a dowel, put it in a drill and take out some . Then inspect and perhaps fire it to see if there is a problem of interfering with extraction. If you have a problem another step is necessary.

Here is what I do if the rust is just surface rust!
First go to your local pharmacy and request to obtain some swabs that are fairly large.
Remove the stock and WD-40 the chamber and let sit for about 15 minutes. After you leave the pharmacy go to the auto parts store and get a can of FINE Grit valve grinding compound. Cover the swab with the VG compound and using hand pressure only work the swab thru the chamber. When you feel that you have done all you can to clean the chamber, point the barrel up and spray more WD-40 in the chamber and wipe out with paper towels or TP. If the rust hasen't pitted the chamber you are good to go. Might want to run a cleaning rod and patches thru the barrel for good measure. This method works for me!

DO NOT, i repeat, DO NOT start with abrasives.

First, use a double or triple patch, and swap the bore with some bore cleaner.. just to establish what's what... turn it several times

take you light and inspect

if that's not cleaning it up then


WARNING WARNING WARNING

CLR WILL remove bluing... be DAMN careful

take the action out of the stock (make sure you notice which screw goes in the MIDDLE of the triggerguard, if it has one.)

get some CLR from the local grocery/hardware store. Also get some baking soda and plenty of rem oil/gunoil/wd40/tranny fuild/unicorn sweat or whatever else you might generally use on your guns.

with the barrel out, put a flanel (doesn't really matter as long as it's natural fiber) oversized patch on a cleaning rod, wet it in clr (pour it over a sink on the rod and patch) and make certain it's not going to DRIP whem you put it in the chamber...

turn the rod in the chamber, with the patch, for about 5 mins.

Remove and inspect

repeat if required.

When the chamber is finished, you the squirt in a mild solution of baking soda and water (test by dripping clr into a can of the same strength.. when it fizzes, it's strong enough)
rinse throughly with water, and oil like hell
