Need Help with Rust in the Chamber of a Model 70

[XD Fan]

My buddy has recently inherited Winchester Model 70 in 7mm WSM. It is not terribly old, but has been in less than dry storage for a while. We were cleaning it today and discovered some rust in the chamber where the barrel is threaded into the receiver as well as a couple of small spots on the bolt face. The bolt face was easy enough to clean up, but the barrel/receiver area is very difficult to get to.

Does anyone have any suggestion on how we might get this problem cleaned up? Is it complicated or hazardous to accuracy to remove the barrel and access this area in that way?

Also, if my nomenclature seems incorrect, I would appreciate guidance in that area as well.

If the rust isn't so bad that it has removed a significant amounts of metal you should be good to go. Just use some brass brushes. You might need to take things apart to get it all. That's what I did on a mauser at least.

JMO, and I'm not a gunsmith.

Good luck!

Thanks for the input, Torabora.

Find a short (12" or so) section of cleaning rod, and a .45 cal bronze bore brush.
Then buy a pack of 0000 Super-Fine steel wool.

Wrap a tuft of steel wool on the brush, chuck the rod in a cordless drill, apply solvent, and spin it in the chamber for a few seconds.

It will take out everything Mr. Winchester didn't put in there without harming anything.

^^^^^This method can be done by hand just as easily^^^^^

I'm always reticent to advise using power tools and have experience to back it up. I have had to replace too many parts because of using them. If you do it that way use a variable speed drill on its lowest setting until you get the hang of it.

Transmission Fluid mixed with a little Acetone is a good detergent to remove rust. Use the brush and the steel wool by hand and dip the whole brush into the Mix I mentioned. When you get the rust spots off run the whole bore with solvent and whatever gun oil you prefer to neutralize the solvent and get the bore clean.
